The best way to find partners is your inner circle, the people who you have a shared success with. Starting a company is like a marriage, you really want to know and trust your partner.
Another place to look is a web site www.gobignetwork.com where you can post a job description for a programmer. They have a “will work for equity” section as well as a volunteer section.
Another place you could post a ad for programmer is www.elance.com or www.craigslist.com. Results from these sites as well as overseas are mixed. You need to manage them and I would not look for partners there.
