Look for some NASA/US Gov RFPs and open contracts for some low level manufacturing/sub-contractor work on their space missions(or sub contract work from prime contractors). Get the necessary certifications. When you do win bids, hire the right people, then provide the services, and money starts coming in. I'm sure there is a banker or financial institution out there that'll hand out funding to someone that actually holds a contract to NASA or a big defense contractor.

There are a lot of companies that set up shop right next to Boeing, and simply provide services to them. Probably all the other big aerospace companies, too. That sounds like a great way to get your foot in the door.

It's actually one of the best solutions proposed here.
