Editing sizes of Garden building images

I would like to have approximately 80 images used from my own photos to show case the different sizes that I offer. I have 3 different designs with many different sizes. I will be able to show you the sizes from competitors but they must be my images that are used and then made to look like the sizes required.
Also will need to have each shed size with a single door and double door. Along with windows and no windows.

There will be further work required as my product portfolio grows.

Will need to be on a white background and have in 2 different colours of the buildings.

Many Thanks
