Contact sheet editing and information

To create colour contact sheets I would need a colour darkroom, paper and chems, and money to pay for the time etc etc. But this is not in my budget or easily done, I could pay someone to create them for me but this would not be the same, I'd rather create the documents myself oneway or another. So I simply photographed the colour negatives (C-41) in their plastic sleeves on a light box using a full frame camera with a 50mm macro and an overhead tripod. This way was the only way I could see working best, I could scan them on the MFD scanner but this would create newton rings because of the acetate sleeve. Either way, I need a digital files which can be manipulated for book output. all I need to do to these is invert the colours and correct the white balance and all should be fine.
