Expert Photo Editing - retouching

I'm looking for somebody to retouch and edit 187 images in total in the following manner:

1. fix light and improve resolution
2. remove background completely so that only the model and the reformer are visible
3. save as .png in as higher resolution as is possible

The same file name and folder structure will need to be retained.

Attached is a sample image - these were all shot against a white backdrop and due to unforseen circumstances, fairly low levels of light.

We are looking for the final files to be supplied within 7 days.
