I used AutoCad at work at lunch to loft the stations of the Freedom 17 canoe that I'm working on. Autocad is the most common engineering design program in use today and most community colleges offer classes in it's use. You might consider approaching the instructor to see if he can suggest a student to do this project for you. You get the stations printed (they might be able to print them at full scale for you) and you help a student defray costs. That sounds like win-win to me.

Just a suggestion.
