dotPhoto does not offer scanning services, but there are companies that specialize in it. Trackable shipping is critical when using this service because you don't want to send your one-of-a-kind memories into the void.
Scanning is a specialty that requires and investment in machinery and expertise. We recommend these two services:
Home Movie Depot makes this special offer: they will transfer all the movies you can fit into a UPS or FedEx medium box for just $299: http://www.homemoviedepot.com/easy_box.php
When considering a photo scanning company, insist on at least 300 dots per inch; many companies scan at 600 dpi.
Of course, this is only a recommendation: Gophoto and Homemoviedepot are independent companies.
If you don't want to send your photos away for scanning, you can purchase a dedicated high-speed photo scanner that scans up to 1 photo per second.
