Koniforous offers good advice.
Could the 3rd party put up the collateral for you? Long time players have a lot of junk laying around. If they trust you let them put up some of that junk. They are also in charge of an alliance? Should be peanuts to them.. In fact the liquid 5 bill should be peanuts to them.

5 billion is a lot to ask for a first time loan. A realistic approach shows investors you've thought things through. This mean you are more likely to also have a viable plan and intent from the start to pay back the loan. The more pie in the sky the less likely.

The benefit to the investor is small.
IF your plan for the ISK is good AND
IF you intend to pay it back AND
IF nothing unforseen happens AND
IF you don't explode for not having a mining permit AND
IF you did mean to pay it back at the start, but it's tough making ISK and you've now changed your mind doesn't happen.
They get 21 back for every 20 they loaned you.

OR

If any of the above fails they get 0 back for every 20 they loaned you.

The risk is huge, the payback is small. Remind investors why you are a good idea, come up with a good plan, sell yourself, try and see it from their point of view. If the roles were reversed what would make you want to risk your ISK on a stranger? What would make you feel confident you had made a good investment?
