our sites were made by in house designers at first, but then we choose to go the pro way and hired people who know what they're doing:
http://www.webinc.com
http://www.scorpiocreations.com
http://www.fdsign.com
lately we're working with fdsign exclusively since the relation cost/quality is simply amazing, and we're planning to have Bruno Dickman and/or Envisionext to do our first public affiliate program. Never worked with Wyldesites but I feel this thread wouldn't be complete without mentioning Mike
btw, I know only 3 people thinking outside the box when it comes to tour layouts, and that's fdsign, wyldesites and dickmansdesigns, that's why we like them
