283664 iphone fbx viewer

I am looking to develop an fbx viewer for the iphone, that can display a 3d model and animation. The user will have the ability to pick which model to view and between a few different animations. The user should be able to loop and pause the animation. Then take a snapshot of the pose and save it as an image. I have more features but would like to know the cost and time of development to implementation of the project described first. Kindly notify me of any problems which may need to be addressed to complete development.
