3d modeling playground equipment

Information for the business: Playgrounds
Industry: Art and Design
Design details: We need 6 objects from another company modeled so we can use that objects in our renderings. The models do not need to be exact since they will serve mostly as a placeholder in our renderings.
We don't need any textures, since we will be using our own libraries.
The different materials should be individual meshes though.

The job consists of
2 smaller objects like this:

2 medium objects like this:

2 large structures like this:

We need 3DMAX files. The objects will be visualized from about 5 m distance.

If this is successful, we hope to find a steady source for 3rd party object modeling.
