Scratch build your own from bass wood, finish them to provide a smooth surface and then mould and resin cast them. More time consuming and it will be a challenge to carve and finish suitably, but the end result will allow you to furnish your carrier with as many aircraft as you want. You could sell a few to subsidise the project costs??? Drawings of most if not all aircraft are available online, and can either be printed out as is and then applying a formula to dimensions taken from them, or printed out, scaled and then photocopied to the right scale.
It isn't that difficult, and once you have done one, the rest are variations upon a theme. Just have some good sharp tools inc a snap off knife and blades for carving larger shapes.
