I'm with TheEnchantedHunter. Invest the money and find a great coach who can help you build up your rep. They are often also musical directors and/or audition and rehearsal pianists, so they have great insight as to what songs are overdone.
For example, I showed my coach my book and he saw maybe three songs he thought were right. We went through a number of composer anthologies and I ended up walking out of there with eleven new songs to work on.
Good rule of thumb: avoid Sondheim, Lachiusa, Jason Robert Brown, because the piano accompaniments are so difficult and if the pianist is thrown off, you'll get thrown off too.
Oh, and just to add to the "Overdone Songs" list: "Come to Your Senses" from TTB.
