I want to build a custom laptop.?

Before I continue, let me give a little background. I have been building desktop computers for myself, family, friends and a few customers for a few years, but now I find myself doing more tech support than anything else and my current laptop just isn't up to snuff with what I need to do. So I figured I'd ask around and see if anyone knew where I could get laptop parts, specifically the motherboard and a CPU. Preferably a motherboard that supports Intel i7 processors, and of course, i7 mobile processors themselves. Thank you.
