I'd love a non-technical co-founder, if I could only find one. Most business-oriented people I meet like being employed. The only people I meet that are interested in startups (interested in building one, rather than having built one, successfully) are engineers with less panache for sales than I have.

I'm in a similar situation as the OP, and to be honest I'd be willing to give a lot away to have someone handle the sales & marketing end.
