One would not necessarily have to get there by ship. In a few years time it will be possible to "get there" by signal. If matter can be transported from one place to another, the possibilities are endless.
I was thinking that one could send material across space to another world. This material would then build itself. It would be programmed to replicate, much as plant life does. Basically, one would be able to send all kinds of stuff over - even robots that can assemble themselves before assembling anything else.
An entire factory could build itself.
One should be able to do this:

Albeit not any time soon.
From this, then, one could signal that plant to start beaming over, say, mmm, Republicans. If it was successful, then other people, etc.

One just needs to signal a spot on that planet. "Paint" it, if you will. This could be done either through light, or if some clever researcher can warp time and space, then faster. Then, one needs to connect with particles on that spot. Then, send over bigger and bigger building blocks, enlarge the area, then sit back and wait for it to happen.
Once a relay station is established, the rest is history.
I think the focus needs to be on this, not on scrabbling around for parts to build rocket ships and for fuel to pump into them.
Maybe a larger corporation could finance this: al la WillE.
