Looking for Help to Automate Monitoring Referral Source Quality

Can anyone recommend someone to set up a couple of automated processes to monitor the quality of some of my referral sources? I want to be able to see whether certain referral sources are giving me subscribers that are sticky. If whether I’m paying for them only to have them drop off 2-3 weeks later. I know it’s not crazy hard to do but is simply above my pay grade( and I want to do it right). Thanks.
