Typically, a new realtor needs to interview at several brokerages and compare what each brokerage offers - type of marketing, type of software used, amount of fees you will need to pay upfront, whether the brokerage offers leads, percentage of commission split, what is expected of agents, etc.
However, in your situation, your biggest obstacle is learning about the new area you moved to. Remember, you are self employed and responsible for succeeding in your own business. Real estate is very competitive and the other agents in your office as well as other brokerages know the area better than you do and will use it against you. You need to develop a plan as to how you will get leads, why people should hire you and trust you, what can you offer buyers and sellers that other realtors can't, and expect leads to ask about your experience and knowledge of the area.
