2D Game illustrations of full-body human characters

I'm working on a game. You have to create full-body characters in a similar style to these: [login to view URL] I will need the .psd source files. Everything must be on separate layers (body parts, colors, clothes etc.) The backgrounds should stay empty/transparent. I need professional work. The eventual number of the pictures are still not known. Somewhere between 5 and 20 maybe. You have to give a price for one picture. The pictures must be in Full-HD. The project budget is for one picture here for now, but later I will order more for the same price. Also, you will have to sign a contract with me, in wich you give me all rights and licenses of the illustrations, so you have only a flat fee for the pictures and nothing else later on. You must have an intermediate English skill at least. The illustrations will be exclusive to me, you cannot upload them or sell them anywhere else. Other details via chat.
