If you have someone else do the work for you, you'll never learn how to do it. You need to go through the extacy of creatiive design and the agony of failure, over and over, in order to be shaped into an engineer of any merit. Assuming you're an engineering student, is this how you're going to conduct your engineering career? Asking other engieers to bail you out?
