It's understandable that you'd wonder how long the document scanning process would take since, inevitable, you'll more than likely need your files and document back as soon as possible. Thankfully, these days, technology is stage where all this work can be done extremely quickly with excellent results, which is exactly what you would expect. As an exam;e, the scanners that we use on a daily basis can scan thousands of documents per day and our company outputs around 3 million files per month. However there are other factors to consider.

You can also request OCR scanning which means that your documents will be made completely text search able so particular keywords can be located with a simple computer text search almost immediately.
So add up around how many documents you have that will need scanning and call up the company or companies that you are looking at working with and ask them for a quote, but make sure to ask how many documents they can output per day as this will give you an idea of exactly how long the process should take. Also ask them about the indexing and potential OCR processing if you are interested to see how much time this will add.

Document scanning is a worthwhile and future proof solution for the office, but make sure you go with a reputable company that offers both good results and speed.
Other tips: Look for the ISO 9001 :2000 accreditation which means that their work is looked over by a third party and ask for a sample of the work to be done so you can get a good idea of who the document scanning process will turn out.
