Common car seats angled front view in Photoshop

Dear freelancers, I need common car seats designed in Photoshop: back seat, front seats angled front view. I will need the original photoshop file. All layers separated (not merged). I should be able to change color of any car seat part and show only one seat, two seats or the entire set. The car seats should look as real as possible. Basically I will create fabric patterns and combine them on car seats to help customers choose a pattern combination for their order. When changing fabric patterns, it is very much desired that shadows that give depth to the image to stay in place and not have a plain flat image. I attach a very rough idea of car seats. The structure of lines on the car seats should be like in the image only of much better quality overall. The image should be large enough so that I can zoom on details and show texture of the fabric. If you need other details, please write in comments section. Thank you for bidding!
