Photo editor needed for photos of my paper sculpture work

I am an illustrator who works with a lot of white cut paper, and I have some old home-studio style shots of a mainly white cut paper book I made. The camera and resolution are high quality, but the background needs extending and the colours correcting, to make it look professional enough for me to use to promote my work, as I can't rephotograph the product itself any more.
If this goes well then I have a couple of other white cut paper things I would like the same treatment for.
