ok, that's better, having some investment and you both being programmers will be easier to sell your idea to potential cofounders. I would say best is to find another co-founder that is willing to take only shares more than 10%, up to 25% would be reasonable if he's good. A sign that he is good would be that he will have good ideas on how to go on from where you are, that is how to best spend your 10k, until the next round of investment. So go out interview potential cofounders with one of the question being this one.
