How To Become A Real Estate Agent In Indiana?

My wife wants to get into real estate. what does she need to do and how much does it cost. I think their is a test involved and if so how much is it and how long does it take to get your license? Also after you get your license how do you go about getting a job at a real estate business. Also what is the average salary for someone in the real estate market for their 1st year and with the way the economy is? is this a good career move for her?
