Science & Industry

The information you need is but a Google away.

Problem is, when asking for advice on the booster industry, you'll get two types of replies:
Those who don't know what they're on about will give **** advice and tell you it's not worth the time and effort.
Then there are those who are in the industry who do know what they're on about and will give **** advice and tell you it's not worth the time and effort because they don't want any more competition.

I'll give you a starter, though - the manufacture of pure booster cannot be done in high sec.

Needs 0.3 or lower security status for the reactor(s)

Investment capital depends both on how serious you are about it, and what your strategy for POS survival is. You could do synth or standard boosters on a small POS, say 200-250m for infrastructure. If your serious about it, your gonna want a Large hardened tower, which is probably gonna be north of 500m by the time your done fitting it. (Note: If someone is serious about taking down your tower, it will go down regardless in the absence of a fleet coming to save it; all the large tower and hardeners do is discourage less motivate attackers, and those looking for the low hanging fruit to pick on) Best place to do it is within range of your PvP support if you have it, otherwise any convenient 0.3 or lower lowsec system.

As for the ATAP guide, its very professionally put together. It does contain some valuable information that is not easily available from other sources, but it also says nothing about the business aspects, and what you would want to do if you intend to make money off boosters. I presume this was an intentional choice by the author, but it means that only about 3 pages of it are useful to the manufacturer (and 1/3rd of that is a chart that you could learn from the info window on the reaction recipes).

Not much to add except ATAP's Guide to Booster Production v1.2. An update to match the new naming scheme and hacking functionality which was released with Odyssey.
