[Space/Spaceships] Getting the velocity/Delta V I want with the tech I want

I've been playing around the numbers some more, and have some updated figures. Mainly by noticing a way to game the system, it's not much, but it helps. Won't stand up in reality, but for a game it's good enough (Cramming 10 fuel tanks into the space of 9 is a physical impossibility)

At worst the fuel to ship a ton into orbit is ~$4,700 per ton, or $2.12 per pound.

Shipping between the two stars cost the company less then $7,000 per ton, or $3.09 while the ships in hock to the bank, or ~$1,100 per ton or $0.51 when the interests paid off.

So it should cost NO MORE then $15 to ship a pound of something between the two stars, at maximum.

For reference I looked up the Australia Post costs to ship stuff, the lowest rate to the US for 500 grams (about a pound) is $10.50, and that's by sea, air freight seems to run to about twice that
