Editing a picture

I need two profile pictures of myself editing. I want to edit out the backgrounds entirely. Ideally, I'd like myself to be completely 'cut out' and so that there is nothing behind me (there is a window, curtain and wall) with a white background
I would also ideally like to try to see if one of the photos would work with putting me infront of a background of books (a stock library shot- that I don't have)
I need you to have had proven experience of editing photographs please - so please include a reference or link to examples of your work in your bid.
I have other photos I'd like to edit in the future, so I want someone good who I can trust to use again.
Thanks!
