Hello and welcome. I am certified both silver and gold and I want to address your question. Since you have been shopping for five years and you already have ample work, I don't see any reason for you to certify. Yes, you might be able to pick up some additional work but that won't make any difference; you can only do so much anyway. After five years you are running on your reputation, and your reputation is what matters.
Mary Davis Nowell. Based close to Fort Worth. Shopping Interstate 20 east and west, Interstate 35 north and south.
