Simple 3D Studio Models

Hi, I would like some very simple 3Ds (3D Studio) Models created for me. Here's what I would like: *** Models should be made with "TRIANGLES" NOT Polygons as they will be used in a game*** 1) 5 Stunt Racing Tracks (for a stunt racing game)- Very very simple models with least triangles. 2) 5 Stunt Racing Cars - VERY simple model designs (max 150 triangles each) Also simple inside view of the cars. 3) 1 Very simple passenger airplane with landing gear out. That's all. Just the models with some colour, nothing else. No textures, no animations, no code, Just simple models. These can be done in a couple of hours I'm sure so please keep the bids reasonable. I will provide design ideas and sketches straight away.
