If you don't plan on having more than a few clutches, I don't think you need more than a good Facebook page to sell well. Assuming you produce high quality animals, and can take good pics, Facebook has a tremendous reach.
I can't believe the kind of garbage dipped reptiles offered on Craigslist, I wouldn't consider animals from there.
Present yourself professionally on FB, and you should be fine without a specific website of your own.
Best of luck.
