Check out Team8 snowboards. Team Eight Snowboards
Out of Portland, Maine I think... Heard about them awhile back. You can send in a high-def graphic and they will throw it up on a board. 2 years ago they only did camber rides, but this year there might be other options. You can customize every little detail of the board. If you are not sure, you can take a board you like from any major brand, record all the dimensions and fill in the "configurator." You can also call them, tell them what board you want yours to ride like, and they can tell you what options to pick to get it as close as possible.
Custom boards for under 400.
