Hey @Ryan Johnston,
I moved down here to Tampa in January with the same intentions as yourself. Got licensed and found a job with an investment brokerage. Best decision I could have made, the opportunities down here are endless.
Down here in Florida, you are required to take a 63 hour course, final course exam, and then the state exam. My best advice would to be proactive and get the course done as soon as possible, so once you get down here you are ready to take your state exam. You also have to apply for your license through the DBPR and get your fingerprints done. Once you have done this and have been approved, then you will be able to take the test.
The only online course I know of is the one I used, "Real Estate Express." The course comes with the textbook, about 20 chapters of quizzes, a pre-exam and a final. Worked well for me and helped me prepare for the state exam (which is not easy).
Hope this helps you out, feel free to reach out if you have any further questions. And good luck on your next move down here to Tampa Bay, its paradise down here man.
