Actually there's a section on this site specifically for buying and selling snakes, I just got a warning PM from just mentioning that I had some snakes for sale on a general forum LOL. I usually buy on Morphmarket.com, most people selling on that site know what they are doing. I would have them ship to and hold the snake at your local FedEx hub too, I've had bad experiences shipping snakes directly to my house when putting a snake in a box on a truck out for local delivery. On Morphmarket you can refine your search to Pastel and sort by price, prices start at $20. You'll probably pay as much for shipping as you will for the snakes LOL. You may be able to find someone else local that wants to buy snakes, maybe you can buy several at a time from one guy and split the snakes with someone else to save on shipping. I usually pay about $50 for shipping.
Personally I like the smaller breeders, just because they have better communication. I've found that most times with the super large breeders I can't even communicate enough to buy a snake, I guess I get lost in their sea of e-mails LOL. Sometimes I wish that Morphmarket had a 'buy it now' button because the way it is you have to send an e-mail and half the time I've found that the snake is already sold but just not marked sold on the website.
