Who would be interested?

So I've been building PC's for a couple years now, and kinda want to start doing it as  more than just a hobby. Would anyone be interested in buying a custom built PC? Basically you specify your needs/budget and I can choose parts to match that, or if you want to choose parts, I can do the rest. 

I'd charge essentially the price of parts + shipping at first, until I am able to build up a reputation.

This is awesome @tempts ! Best of lucking with selling these man, you got some skill if your building PC's like.
