I have already done numerous model plans on a commercial basis. Couple of the vendors here are currently selling copies off my prepared plans. But contact a few of the folks noted above in either of the forums headed by Thunder.

Finished price will sort of depend if you want something to re-sale or just a one off. You need to be very specific as to your intentions. Then too they often do NOT move around or otherwise adjust things to fit some revisions due to poor flying prototype, too many parts, too complicated, etc. For my customers, the get only three tries to get perfect. One Mfgr. took five times. That cost him.
