The signing services that are honorable and treat me well are my secret. Why? Because it is so competitive out there that I cannot afford to give away my cashflow providers for fear that other notaries will horn in on me. Selfish? No. Prudent, For sure.
My advice is to apply the good advice for picking your signing services offered on this forum and check them out before you do any work for them. Make some phone calls if you have to. Keep good notes and stay on top of increasingly stale payments. Build relationships and always do good work. Admit your mistakes, correct them and take your hits when you have to.
