Advice on becoming an agent

I noticed on other posts here that many of you folks are very generous with advice, even to newcomers, so I wanted to ask for opinions. I'm 42 and semi-retired from my job as a consultant, and am considering becoming an insurance agent in a coastal Florida town, where I live. One of the biggest motivators I have is that I and all of my business contacts here feel very poorly served by our current group of agents. The usual larger firms are here, and 4-5 independent agencies, but you'd be hard-pressed to find anyone who was truly satisfied with their agent(s). I own a number of residential and commercial properties, and the list of troubles I've had with the agents and their employees is too long to type.

So seeing a need, I'm looking into filling it. The focus in this area would be more on property and liability, and less on life and health, as there are loads of rental units here, and many people live elsewhere primarily.

I'm not looking to make tons of money, just provide a great service at reasonable profitability. And perhaps to reinvent myself a bit with a whole new career.

Here are my questions:

1. Am I crazy to think I can do all the bookwork/licensure and then start my own agency?

2. Is it wrong to expect a reasonable profit if the majority of the policies are property and liability?

I'd appreciate any comments or opinions. Thanks.
