As with any business you must consider what you call "market". Is your market the swap meets? The big breeder shows? Or local/regional herp classifieds? I don't believe the market is saturated in any area, yet. If so, you need to increase your market area. If you live in Florida or California in areas where your competition is based, you will have a tough time. However, if you branch out to advertizing in other regions say Arizona, you may have better luck. This is an example of course. You need to determine how and where you want to market yourself.
The key to marketing any business is having a USP or Unique Selling Proposition. You need to identify yourself from the competition. You need to create or identify your product so unique to others that you create a separate demand, then you can command above average prices. This is successfully done by Ralph Davis, NERD, VPI, Reptile Industries, etc in varying markets. The simple way is be the first to sell a pastel x caramel or other combination. Or you can provide expert advice and service that the first-time breeder usually cannot provide. This is the basics of marketing. I have paid prices for animals far above going market prices because I am getting something better (ie good eater, exceptional appearance, captive bred, etc). Of course I am a hobbyist, but there is a business sense that you need to maintain if you want the hobby to support itself. You also have to be patient in this "industry". Why let an animal go for cheap if you don't have to. There is seasonality to herp breeding and sales for the most part. If you sell to pet shops this is even more apparent. Summer is bad, Christmas time rocks. So keep looking around and remember that sometimes, people get what they pay for. The question you should ask yourself is, are your customers getting what they pay for, or more or less?
