Avoid the problems with Open Licencing and Developement, this space is for free. seek a embedded designer with AVR 168/368 microcontrollers, you can hire a designer on freelancer.com, many eastern european, south asian, developers bidding for projects around $300-500, its cheaper than using any Aussie labor.
Also by paying the bill you have 100% control, Arduino is not the place for commerical embedded design. we are here to tinker not make a income.
Although true for you, it might not be true for all, there are several commercial people on this forum (behaving quite well, thank you) and I have seen students here that would like to have such a job very much just to pay for their hardware ...
That said, there is a special section for gigs & collaboration under Community...
I have a friend who got a product written by someone at coders-r-us or whatever, and to be fair the product was delivered at a price that would hardly have paid me for a day.
BUT
It took forever, maybe even a year I forget now. And EVERY tiny change takes a month.
Last I heard they had version 2 out, and had been waiting 3 months for the source code.
This probably isn't common (one would hope not) and certainly there are issues with hiring people as well. Just putting another perspective on the "argument".
phonetic:
we are here to tinker not make a income.
I disagrea with most things you said there... some of us make an income by tinkering. Also, why should they not prototype with arduino? Thats what arduino is designed to do, after all :-S
