Congrat's and the best of luck!
I would first choose the area you want to work in. Many Broker's claim training, mentor's (you have to split commission39;s with these), etc.
2nd - I would go into the offices and talk with other agents and then interview the Broker. YOU do the interviewing because it's YOUR commission split/percentage that will be paying their salary.
If you like the "office" and agents you've talked with, hang your license there. The majority of agents in a "good" office are extremely helpful with newer agents. (My office anyway).
Also, check what "FREE" training is going on at your local Association. Continuing education is a must!
