What kind of practice/business do you want?
Does this seem to fit what you have envisioned for yourself?
First impressions: It's transactional oriented (not necessarily a bad thing).
IMO, You'll be competing on price. (Any website where you can request a quote will compete and die on price.)
How many other agents are in your area? Have you considered taking a few of them out to lunch to ask them about the company? (Websites are just so "one-sided" that you need to get a more in-depth look and perspective.)
Any franchise fees? Non-competes? What happens WHEN you leave your business? (Yes, you will leave your business due to termination (you or them), death, disabilty or retirement.) Who gets your clients/policy-holders?
It sounds like the "Edward Jones" for P&C agents to me. Just go into it with your eyes wide open.
