I'm working with a client who uses QB Enterprise for the last 10+ years. He has a lot of transactions and when his file size gets too big (it's currently at 4GB) we've used a company who peels off a few years of data and help us shrink the file.  We've done this a couple times over the past 6 years and the company we used in the past is not available.  

Can anybody recommend a person or company who has the expertise and experience to take on this project.

Thank-you

Brian
