kit cutters!
This is a F.A.Q. in these forums and probably the the two most recommended cutters are Mace Gill of Aeroplane Works and Larry of Precision Cut Kits. There are many others but these two seem to get the most nods from these forums. Both have websites and I think they both list kits in stock. I do not know if they have your particular subject but I do believe they do custom work also.
