Can I be that guy? Ok...I'm gonna do it.

"put fuel in it"

Well said meytal. On point and your figures aren't far off either.

To op: welcome to wspace. Stay for a while. Tell your friends. We're all 'friendly'.

What is the problem, financing the fuel or hauling?
I would try to sort hauling if that is the issue. Here are one or two things you can think of doing if you can decently haul stuff in and out:

Put any reaction setup into your pos to reduce pos upkeep. The reaction needs to be profitable in terms of materials brought in vs exported materials. Even if your reaction produces 20 mil per month its money you can use for pos fuel. Look for all reactions not only wh sleeper gas.

Do you have POCOs sorted? having no tax on pocos will reduce import/export taxes and it adds up in long run and if you have barren/temperate/lava/plasma planets you can make them into factory planets. Factory planets earn more then extraction but your hauling m3 will skyrocket like mad. Having 0% tax on pocos will allow you to compete with high sec factory farms at least.

Example: With command center 5 you can fit 3 launchpads and 20 factories on a single planet. Hauling in mechanical parts (6000ish isk x 10 for 1 factory = 60000 isk) and consumer electronics (7000 isk x 10 = 70k isk) and then making robotics (3 pieces made from 1 factory = 3 x50k isk = 150k isk) and selling will get you 150k-130k=20k per factory per hour, thus one planet is 20k isk x 20 factories x 24 hours x 7 days = 67 mil per week, add more planets and you should be able to fund the pos easily. Of course my numbers are off and need to be substituted but hopefully you will see how much more better that is compared to extracting and making low tier garbage. Be ware though your hauling m3 needs will skyrocket like mad if you go this route though.

Production. Get couple arrays, online the one you need at the moment store the rest. I would start looking for faction ship bpc-s on market. Ship bpc-s take decently long to manufacture so you dont have to micromanage it all the god damn time. One character with material efficiency 5 and mass production 4 in theory for example should be able to make some money. The prices and profitability will change with crius so you need to do the math yourself. If you can squeeze some profit out that can help financing the tower. Also reprocessing minerals you mine in wh may potentially cut down on hauling. I dont know the m3 but maybe is maybe. Do some math and see for yourself.

Yeah, it's really hard to make accurate estimates because so much depends on skill, fleet composition, numbers of alts running, system effects, etc. So far, the best I've been able to see per account is around 100m ISK/hr for shooting Sleepers in non-Magnetar C4. We're still really bad at escalations, so I can't even begin to estimate what that should bring in per account :)

I did check prices yesterday, and harvesting C320 with a max-skilled Venture/Prospect pilot is over 100m ISK/hr. AFK rock mining can produce a surprising amount of ISK, though expect to lose a lot of mining ships; don't use anything expensive if you do this. Lowsec ores are the best, probably due to nullsec mining bots flooding the market with minerals from the ABCs. (Ice mining is also up, and is only going to increase when Crius drops, but that's irrelevant to W-space).

Hybrid polymer reactions and T2 moon goo reactions are really hit and miss and the market fluctuates fairly rapidly; they are worth it if you produce/acquire the materials yourself with minimal outside purchases to squeeze out just that few more ISK before selling to the market, but probably not worth it if you import everything. Patience is key there, knowing when to dump and when to hold. I've given up polymer reactions and use the CPU for industry, producing what will sell at obscene profit margins and decent theoretical ISK/hr. A broad range of options is best to avoid crashing any one income source.

The best way to make ISK, though the least predictable and reliable, is to shoot people who have been shooting Sleepers for the last two or three hours, take any shiny that drops from their ships, and then harvest their proceeds. That's a great way to go "mining" too :)

All of this is because it seems like the OP was mostly concerned with costs for fuel, which indeed have gone up since the ice belt changes, approaching the better part of a PLEX per month. You can probably save 50 mil per month in fuel costs by manufacturing it yourself with decent blueprints, but as mentioned, the hauling needs are greater if you bring everything in from outside, at least until Crius drops. After Crius, both hauling efficiency and profit will make in-hole production desireable.

Or just sell PLEXes and buy fuel :)

You and your 3 lady corp should leave WH space.

Whatever for?

I think the problem is the "3" part. Overhead gets cheaper the more people are involved. With three, you're looking at a lot of overhead per person.

If it was me, I'd daytrip or nomad with only three people. You could live out of an Orca or even an industrial, especially with the help of mobile depots.

As you are going to have haul ice in you are better off going for max profit on the PI. Then haul it out, sell it, and buy fuel blocks.

Bleh.....this whole situation is not getting any better.
We have tried to make some changes but have suffered some catastrophic losses while trying to do so.
Linda claims she is having lag/connectivity issues that caused the losses.
We may end up losing everything (or what is left) unless we can get a substantial loan or something.

All three of you are welcome to come into my C2, you'd have to join our corp mind but you can have a pos to yourself and with us all here you shouldn't have problems fueling your pos's
