Photo editing - 40-50 photos

I have a number of photos from a recent shoot edited - backdrop was creased and has spoiled some of the images so would like it cut out and replaced with a clean white background - but I am unable to edited these myself due to time constraints. Also some of the images are needing lighting corrected - we did a baby milk bath and the milk/water needs to be pure bright white but don't want to ruin the rest of the image. Looking for a high standard and high res. files to be returned. Ideally looking for the photos back within next 24 hours.
