Arduino + magstripe reader + lcd + printer + pos programming and soldering + keyboard button

Like the title I WILL PAY FOR THE PARTS + WORK . I have a pos terminal box empty just with lcd printer and buttons that i want to develop my own prototype for pos terminal. it is a verifone vx 670 machine box with only lcd + printer+ buttons+ magstripe reader. i want to put a arduino in it and want it to work like a pos but phase one will be just dummy for testing and phase two for about 1000 USD will be with server connectiviy If you agree you must agree making how to manual for soldering on all assembly and source code
