Every big enterprise like this needs a crazy amount of money- there will be no short supply of things needing payed for, or people needing to be bought off or bribed I'm sure. 

What I'm going for is someone who knows what they'll need when they start setting up on the planet: food preserves, medicine, water preserves, supplies for setting up camp and establishing a base to work from. Also potential plant and crop stocks, and simple but increadibly nessessary multiuse tools. Someone who's been dreaming of going to mars and living on it no matter the expense and a whole lot of time on their hands to plan for it. 
(This could also include the womb thing- but i'd like to know more about it as i'm not exactly sure what you mean?)

I could also play an excon character who's involved with smuggling the weapons and such and such you need. Someone who's looking for a better life far far far away from earthly crimminals and gov types and willing to do whatever it takes to get off planet. Whichever works best for you. Or both! I'm easy!
