Ebay Question

I have this lady contact me through my auction I have on Ebay asking if I can make her a Michelle for the same price that I sold my Michelle but give her brown eyes and darder hair. Is this ligitmate for her to do this? How do I handle this without getting into trouble with Ebay.

Thanks,
Dianna

Oh Okay thank you. I just never had someone approach me through ebay before.
