tough to "shop" for a local, mostly they will be shopping for you
and it's not all it's cracked to be, believe me
want to bet next week's NFL on Wednesday afternoon? Tough shit call back sunday after 11 AM. And good luck collecting if he doesn't feel like paying you. No RX, MW, SBR, etc to arbitrate for you, your arbitration is that he hangs up on you every time you call.
Unless they are giving you way off lines, you are better off playing the offshore books IMO
Anyway, the only way to do it is to find someone you trust and let him bring you in under his guy. Otherwise you have no idea who you are dealing with. Reputation is everything. I would look for guys who have been in business at least 5 years and have a great history with their clients. Real tough to find in most cases
