Need FBX - GMF (my own format) converter (paid work)

I am looking for someone to write a converter to load FBX files and save them in
my own format.

Here is a preliminary spec:

The idea is that you can load this straight into your engine, without any of the
fiddling around that other formats require. I haven't got all the animation
stuff down yet, but I am thinking about just having a set speed with one
animation key per "tick", so the engine is always just performing an
interpolation between two regularly-spaced keys (instead of animation keys with
arbitrary placements).

This is a paid job.
