Usually it takes about 2 years to get a female to a proper breeding weight. Even if the female grows rapidly, many breeders will wait until the 2nd winter just to be on the safe side.
These are approximate female prices from my experience, all breeders will price differently.
-Cinnamon $350-400
-Spider $300-400
-Pastel $175-225
Some breeders will also go lower or higher depending on quality, but generally pastels will be the most inexpensive. My female spider was 325, but I have seen 'selected' spiders that have nice patterns up for 400. It really depends and varies.
