It depends alot on the technical sophistication required to implement your idea. If it requires a good deal of technical sophistication, you are going to have to locate a good technical co-founder and that's going to be relatively difficult. This is a good place to start and maybe craigslist when you get more serious. If you really want someone to come on board, with no prior personal connection, you are going to need to be really open and up front with your idea, what you are offering, what would be required, and what works you've done, and plan to do. Such a technical co-founder would need to be convinced that you can handle any and all non-technical things completely. And if you can pull off a sale like that, you'll probably make a great non-technical founder :P
