kaytrim for one makes custom panels here, his work seems popular so must be competetively priced . theres a thread on his work in project announcements 
Kaytrim is an amazing guy to work with. I can't recommend him or his work highly enough. I've also worked with knievel (don't know if he's still doing custom work), and timoe (mini sticks take most of his time these days), and both are top-notch builders as well.
The forum is actually full of people willing to sell their services, but I'm only familiar first-hand with these three.
