Photoshop Retouching

I need three photographs retouching, all three were created under lighting that meant banding appears across each of them.

All of the detail is there - there are no areas in the banding where either highlights or shadow detail have been lost, so should be recoverable.

They're relatively large files and can be supplied in RAW, TIFF or JPEG, all produced on a full frame 24mp Sony.

I need to have the finished files by 10th December.

Thanks.
