Need Data Entry Team-Look up website contact info

Hello We need a data entry team that will be able to take excel files we provide, which will have 1000s of domain names. Your job will be to then do "reverse look ups" to get contact info for that site and if that's not publicly available. You will need to go to the actual website and get the "contact info" manually and then update it next to domain name of each site in the excel sheet we send you. We have many domains to do so this will be a long term project. At least 6 months. Thank you
