You may want to try getting into the TGC Store with these, depending on how well the texture is when you're done. It wouldn't hurt to give away one of them for free, so people can see your work before they buy.
I would also suggest packaging it all up in a pack at a discount from buying them all separately. As far as selling them on your own, without access to a store, you can try putting them up on Turbosquid, or www.the3dstudio.com (they give a better percentage back to you).
You can also join a few other forum to show off your work, get tips, etc.
