B&W Photo Retouch, for Archival purposes

1000 Old photos are being archived. High res, 300dpi or better. Scanned from old prints. Have minor imperfections in images, most have dust and spots to be removed, others have minor tears and stains, and just a few have significant restoration work. Most are b&w. We want a few colorized. Would be VERY nice to have some of the nicer images blurred on the edges in square or oval shapes and also nice to have some sepia toned. This is not a rush project, as all the images have not been scanned yet. I would like to complete this project over the next couple months. Payment would be in groups of 100 completed photos. I've uploaded two of the more DIFFICULT images, again MOST of these images will NOT require significant work.
