Simple Chrome Ext or Userscript to Show Notes

I want to maintain a list of Client Names and Client Notes in an online sheet. The chrome extension would monitor the webpage the user is on for that client name(s) and show the associated note(s). The client with note could show up in a status bar at the bottom of the webpage.

An example of the webpage the user may be on is attached. There may be tables of records each with client names or an individual recored with one client name.
