I need an experienced professional to replace background on images. +optimise for web

I have some Pictures needing background replacing to give nice feel/look to main website galleries. Some for colour / light correction.

I want 1 main pic needing background replace with five to ten other pics for colour corrections. I have lots of pics. but want to find good graphic designer who can understand the scope of the job.

All pictures are of food. Some low res, many bad pics. Some are good/ high res but not many. If you would like to know more please ask. =D

examples of quality of images. I f you want to show me what you can do would be fab. I would like soft focus horizon with white backgrounds - thanks
