Add drawers to product pictures

Hello info: So im selling professional kitchen equipment. Im selling refrigerated counters, with 2 doors/3doors/4doors. However you can also order the counter with drawers, but the factory where i buy the counters, dosent have any Pictures of the counter with all the drawer combinations. The job: So i i have a Picture with doors, and i need them replaced with drawers, some Pictures have drawers but i need to add more. In totalt i need around 30 different models made, with all kinds of combinations og drawers. Ive added some Pictures that should explain how you can do it, I also tried myself, however its not good, but it shows that it can be done. Requirements: Before you get the job, i want a exampel of the way you want to do it, show me a good solution on how the drawers could be added into the Picture. If you dont supply me with a exampel, your offer will NOT the accecpted! So try to add drawers onto the Picture that is called "add drawers...." I need the project done within a week from posting this. I need the phoshop files and also jpg versions. Thank you :)
