edit photos

I have a few photos that need some editing. Some need a background change, while some need to be converted to black and white effect. I have a dslr and i click photos occasionally (personal use only). So I need a photo editor every now and then. I am looking for someone who has an excellent creativity and and suggest ideas on how to convert dslr images into next level good looking impressive images. Most of the time, the work is going to be less but frequent.
