There are hackers out there looking for a "business guy" to "marry," but... the "business guy" has to bring more to the table than just an idea. If I partnered up with a "business guy" I'd be expecting somebody with some serious chops when it comes to prospecting and selling (and closing!), some useful connections to potential customers, partners and/or investors, and some knowledge of how to do business development and marketing. And if he knows at least a little bit about accounting and taxes, that would be a bonus.

But wanna-be Jack Welches who think their idea alone is enough to stand on, "if I can just find a hacker to build it" are a dime a dozen. So don't be surprised when you don't find a veritable onslaught of hackers lining up to beat down your door.

Anyway, to answer your question "Where to find a good hacker?" Well... there are lots of places. Starting here is a decent bet, but look for meetups in or near your town... if there is a HN meetup, or any technical user-group (Ruby User's Group, Java User's Group, Linux User's Group, Perl Mongers, whatever) go find them and start hanging out with those folks. Use LinkedIn, poke around sites like Quora and the various StackExchange sites... just don't be too obnoxious with the solicitations, or you'll piss off people who might otherwise be willing to help.

CS departments at area universities might give you useful leads as well. But read this:
