I rarely do color but it seems like most film processors also can put the films on a cd. That may not be the desired quality as compared to a scan but at least it is a backup. When you think about the huge volume the PO or shipper handles, a very tiny percentage of loss or damage translates to quite a few parcels. I had an experience with FedEx once where a roll of transparency film was lost despite being sent overnight and with the tracking showing that it was at their facility. The pictures I had taken could not be retaken. I still use that service but don't forget Murphy's Law.
Scanning a roll of 35mm film on the 700 shouldn't take an incredible length of time if you are not doing manipulation. You might consider scanning the most important frames just in case.
