I need advice organising and digitising old photos

Hello I have approx 1000 photos all mixed up from early 1900’s up to about 10 years ago. I’d like to digitise them so I can stop worrying about loss or damage. Are their any services out there that will sort them all and scan them for me? Can an expert tell from the film/paper/watermarks/negatives enough to put them in a timeline or batches? Thanks :]
