Hello,
Being able to extract the data of all profiles/customers is an important and challenging tasks. It could take quite long if not run appropriately. I've built several of these tools to help several customers extract data of products from platforms such as Ebay, Amazon, Alibaba, Express; or to extract information of computer scientist within UK from 3source.com. I've found those tools should be easy to use, as to require little or no knowledge of programming; and easy to understand, being able to provide the required data without being confused by the terms.
In the last project we were able to download about 100 records per minute. Of course this parameter changes according to the complexity of the profiles and the amount of information in them, but I could say you can get a tool that will allow you to extract all the information you need in a short time. And the best part is that you can get that tool in only a few days (up to 3). So it won't take you long to get the job done and move on to the following phase of the project.
Looking forward to working with you,
Felipe.
