How does a know-nothing like me pick the “good” from the “bad” offerings available?
If you have no personal contacts, you can call a brokerage firm directly. I would suggest calling your local Wells Fargo Advisors branch in your state and ask for the broker of the day. Research Muni bonds and ask leading questions. Most FAs concentrate on mutual funds and annuities because they have a larger payout (commission).
Find a fixed income broker that has years of experience with munis, corporate bonds, and federal agencies.
FYI If you are in Arkansas, I'm your guy ;)
