You could not be possibly looking at the worst time of the year, you are looking for breeders when the majority of people who have them are simply breeding them. To buy breeder size animals the best time is after breeding season not right before or in the middle of it.
Look Morph Market you might find breeder animals but before rushing as yourself what you want to work with, what is your budget, can you afford breeding, are you prepared, do you know that market well enough that you know that what you will produce will not be another of those animals flooding the market making it almost impossible for you to sell, do you have a feeder colony ready etc
Putting 2 snakes together is the easy part.
