Create a plugin for us to import models with its own skinning and animations

Hello, i am looking for a 3d programmer who knows how to work with 3dsmax SDK in order to create a plugin for us to import models with its own skinning and animations from an in-house format. we will be giving all the information needed to accomplish this task as well as the source for the file structure and everything needed of how the in-house file works , if you do not understand please leave your message here

we need a tool that can covert the game format (mesh and Ani) to a readable format in 3ds max 5

we already have the structure of the game files format (mesh and Ani)

Well 3ds max 5 because we have plugin that transfer 3ds max 5 format to our game format

We have a plugin that can export 3ds max format to our game format, all we need is another plugin to import our game format to 3ds max so we can edit or make another one like it so our game can read it
