The best way is to use your local camera shop, most do film transfers and you could always ask to see a sample DVD first before parting with your cash.
Jessops do it as well as these places I cannot recommend any personally these just looked reasonable
I used http://www.cine-to-dvd-transfer.co.uk/index.ht ml they charged �1 per minute of film. Therefore 10 reels is approximately 40 mins so that's �40. I had a lot more 8mm films done than that. I suggest if you are unsure (like I was) then get them to convert a few minutes for your approval. They did mine free of charge and that was 16mm film.
Thanks alot Andyban I have since had them done at this company, and they made a wonderful job, cleaned them up, and added appropriate background music.
