Textures onto 3D shapes

Good morning,
We have three table tops that need rendering in approx 40 different materials.
The shapes are very basic - standard rectangle, rounded rectangle and oval.
We have all textures/materials as high resolution images
I have some photography which may also help in terms of what is required.
I need these provided on a transparent background so I can drop them onto photographs of table bases.
Please provide a sample of your work in the proposal as we will only consider freelancers who stick to these proposals.
