Find a local photography shop. Look it up online or, if you've got one, in the Yellow Pages. These shops were the ones that used to sell camera equipment, but have pretty much gotten out of that market due to their inability to compete with the big box stores and the online resources available.
Many of them now do photo scanning (slides, negatives) as well as conversions from other media (8 mm to DVD, etc.) and other photo-related services, such as prints from digital media to canvas. Wolf Camera or Ritz Camera may even do this. Where I live, there is an independent photo store that does remarkable work for a reasonable price. They also tend to have very knowledgeable people that work there who can assist you with nearly all of your photo needs.
Good luck.
