Quiksilver have a shaping team which consists of 7 pro shapers - Phil Grace, Mark Richards, Simon Anderson, Brett Warner, Mark Phipps, Darren Handley and Wayne Lynch. They usually shape really high performance shortboards for surfers who can really rip.
If you google their names you can find each shapers main website where they can shape boards for you. Also you can find some 'Quiksilver Boards' shaped by these guys on

But like its been said above, Surf companies like Rip Curl, Quiksilver, Billabong...etc will give jobs to pro shapers to make a few boards with their brand logo on it.
Im pretty sure that these big surf companies would pay the shapers to make boards with their logos on them and not take any of the shapers profit. Its just like advertising. Thats what I would think any way
