I selected USAchiving and Imaging because of their customer recommendations and their fair pricing. They were able to make my deadlines and accommodated us when we added 5 more files. At the end of our scanning job, we needed the intact files back. This is not a usual thing for them and the files returned with loose pages and not in the same condition as they were sent out. they graciously took the files back and tacked the pages down for an additional cost that seemed reasonable.
Now that I am living with the scans and the files, I am finding that the scans are inconsistent in their labeling which just took away some of my confidence that my files were really fully captured.
