There are excellent aircraft model makers in the Philippines. Fifteen years ago I had around 25 large King Air 200 models made for US$25 each!
Not sure now who you should contact. There was a Scandanavian guy, ex Stirling Airline DC8 FE, who owned a restaurant on P Burgos Street, off Makati Avenue, who had all the model making contacts, but I'd imagine he's gone now.
You could try to contact manny Cortez at Olympic Aviation + 63 2 833 4608 but even that number may be too old.
Models from Europe and the States are prohibitively expensive!
