Suing for Overtime?

An unidentified submitter asks: "There is a federal law that requires all non programmer-type jobs be compensated for overtime. Last year, over the course of a year, I have worked 500 hours of overtime without comp time, bonus, or paid overtime. I have since left the company, and currently I am attempting to sue the company for lost wages. Has anyone ever been in a similar situation, and do they have any advice/tips? Also is anyone aware of good computer/IT labor attorneys?"
