Thanks for the update on the board, excellent to hear that it is progressing.
To help with your time limits, perhaps consider seeing if others on here are able to donate time. Manuals and drivers could be done by others if required, to let you focus on the design.
With regards to money, would there be a problem with setting up a paypal account to receive donations to cover your beta board costs/or supplement them at least? You could always freeze it when you've reached the required amount (to avoid it building up to silly money) until there is something substantial being produced.
Also, since they are two sided boards, there are huge number of places which should be able to produce the PCBs for testing, I expect if you contacted a university they would be happy to produce them, perhaps even get a few interested students involved to document/build/test for you.
Obviously once you have beta boards you are happy with, I've heard ebay is quite good at raising money for larger runs (apparently)...all you need is Gert John Hancock on it.
