marmoset baby 6 weeks

I am sad to say of a tragedy that occurred, and as much as I don't want to sell the baby, I feel I need to. The mother marmoset died giving birth. Only one baby survived. I have been fostering it from 2 hours old after birth. the baby is now 6 weeks old. I have not had it sexed yet from my vet, so unsure of the sex at this time. Asking $3000.00 very, very tame, sweet and playful. Will sell locally in the Kansas City area only.
