Why not ask if anyone in the modeling forum could help you. You could start with the Wings forum, lot's of nice people there. Building that plow is no big deal, what probably takes most of the time is to texture it but if you can do that yourself I think that you could get some help with the rest. I might even help you myself. ;) If you could find an image showing the other side of the plow it would probably help as I don't think that the blade is symetrical.
