Photo retouching

Small retouching required for c.35 images from a photo shoot - small perspiration stain required to be removed from a cream dress worn by a lady in each image.

Please state turnaround time for the job and the cost per image or per job preferred.

Also, a couple of test images will need to be retouched so that I can see the quality of the work that will be produced. if you are not prepared to do the test work please do not reply.
