Female marmoset

I have a three year old female white tufted common marmoset she is tame i think she needs a male friend. She well come with paper work,cage, marmoset powder diet, formula,diapers, heat lap and incubater. I love her to death but want an animal I don't have to cage when I am gone. I want to trade her for a peer of fennec foxes or a tame bigger monkey (capuchin, java, vervet) but pretty open. No shipping pick up only but welling to meet. Also have pic's.
