Personally I think you would make more money taking apart bikes.

I have bought a few bikes just so I could canabalize them for the parts. I once bought a Kestrel TT bike with Zipp 404's and full Dura Ace 7700 for $800.00. I kept the components and sold the frame for $300.00. I could have easilly sold the wheels for $400.00 and the Dura components for at least another $400.00.
