create a 3d design

We need to create/design the following character of a cool college professor - A male, in his 30's, having casual clothes like a button down half sleeved shirt, a tie, jeans trousers, sports shoes, with shabby hair like albert einstien. Age in 30's gives the youth aspect to the character; Shabby hair like einstien - makes him look crazy enough to be a scholar with the knowhow in his field; casual clothes connects the audience to him as all love seeing a cool professor. Will need the work in FULL DETAILS of the character (front & back of the character). We will need the source files of the completed work before we can release the payment.
