Yes you can save money by doing it yourself but you save about $3 for every hour you work. This is why I recommended you outsource the work to a professional service. Minolta, Nikon and others used to make a 100mm bellows lens and attachments for re-shooting film. One solution gif you have a dSLR is to resort the images. You want decent resolution and dynamic range. Good 35mm film scanners are not easy to find nor are they inexpensive. Yes yo can buy a scanner but realistically if you have many images to scan you are not going to get it done unless that is all you do every night and weekend for weeks or months plus you need to buy the scanner. The scans done in the US cost more but have a quicker turn around. They do the scanning either in India or in The USA midwest some place. A real human looks and does about a minute of work on the image. For that price they actually do some hand work on each frame.
Some times they drop prices to maybe 25 cents per frame. You can go to heir web site and look at prices and service but WAIT for one of their very frequent sales. It takes a few minutes per frame at least because you have to at least adjust the color and exposure and maybe some minor dust/scratch busting.
