Create Product images from designs

We sell decals for Macs, iPhone and iPad. We have several thousand designs that i need artfully placed on a background image of the corresponding Apple product. The designs are available in a drop box folder as an AI or EPS vector file You should take each design and create four versions - 1 for Mac, 1 for iPad , 1 for iPhone 5C and the iPhone 5S - these files should be saved as PNG files with 2 layers so they are easily editable. The designs should complement the Apple product - not just be dumped on it. They can be resized but not cropped or modified. You should then save the files with the same name as the original design file but with an extension to identify it - for example [login to view URL] [login to view URL] etc I have uploaded some samples also of the quality of work we expect. Once the designs are completed they should be moved to another dropbox folder - which is called Awaiting Approval I will then approve them. If they are not approved i will move them to another folder called Rejected - these will have to be redone. This is very very quick work and you should be able to do 15++ designs an hour (I have done it and it takes approx 3 minutes for 4 designs) If you are a team this is also interesting as i need many designs done!
