Create post box images from files supplied

I'm looking for someone to create some wedding post box images from files which we will supply.

In total there are 42 designs which will need creating.

The image will need to be on a dressed back ground rather than plain white.

The postbox itself measures 22 x 22 x 29 in size, it has a removable lid and the front is printed with an image.

The lid has an organza ribbon around it and says "Thank you" on it.

Attached is what we currently have but this was a larger box, we are basically making the box smaller.
