Scheme Designers did a great job for me, and charged less than $1000. The detailed instructions for painter were excellent. I think scheme complexity has a lot to do with price.

Scheme Designers? They want $1400, how did you get a deal?
Ray from http://www.designeye-q.com/ did my scheme, and he was great to work with! I couldn't be happier with the results. Lots of 3d renderings of the options and tweaks as the design progressed.
I don't know what he charges, as my paintshop (www.midwestaircraftrefinishing.com) provided his services with the price of the paint job (which was also FANTASTIC!)
