a captive bred female at that size could be pretty pricey, upwards of $150 depending on how nicely marked, what sub-species, etc. Wild caught large females are sometimes available for considerably less, but are extremely difficult to acclimate to captivity. They're highly prone to fungal/bacterial infections, difficult to get eating, and often have a high parasite load, so veterinary care should be factored into the price before getting a wild caught. If they can even be legally obtained, which is questionable.
