Mike6567,
The professional workflow is a wet mount drum scan followed by a largely manual retouching process on anything major left.
Photoshop is a wonderful tool, its algorithms keep on getting better and better, but even the pros don't batch process the fiddly stuff.
Assuming you don't want to outsource the entire workflow, I would strongly suggest you at least outsource the scanning professionally. That will give you a fighting chance at minimising the amount of retouching needed (or at the very least give you the peace of mind that you've got the best possible scans and then you can take your time over the retouching).
