I have 4 files that I need to be rendered. (3x skp files and 1x 3ds file)
Each file need 3 renders.
1- Side view
2- Front side View
3- Back side View
Render need to look photo-realistic but with no scene.
Background needs to be transparent.

Budget is $40. deadline within 12 hours.
Please check files for examples of render angles.
