I have used Aim High Model Shop in Angeles city for many custom models, B747, LR45, B777 to name a few. All turned out great. They charged me $50 each last time (9 months ago) for 5 custom LR45's painted to match pictures. It seems if you get lots of 5 or more the price is around $50 each. Never checked the price for 1 or 2 because for the price getting 5 was not an issue. Never had a problem getting rid of the excess.
