Starting your own agency is not quite as hard as it sounds, it's harder! With that being said, It can be very rewarding. For the typical agency owner, it's not a 9-5 job.
You'll need to decide whether you are going to be a captive agency (yuk) or an independent agency. Are you going to supply leads to your agents? If not, you still need good lead sources for your agents to go to. Are you going to have an office for your agents to work out of ? Are you going to have the agents turn business in to you or straight to the company? These are just a few things to think about.
You're going to have to be the "go to man" on many things, wear many hats that is. You'll need to be the rock when it comes to positive attitudes. Your going to have to be the most knowledgeable person there. You're going to have to know your products and be able to teach them. Don't forget your Monday morning "rah rah" meetings, they actually work.
Your going to have to be on the look out for new products all the time. In the senior market, the med supps change constantly as far as price goes. Companies tend to have huge price increases sooner or later, so you'll have to be ready. Never put all your eggs in one basket. You'll need several companies for FE,
LTC, Annuities, SPWL, etc.
These are a few things to think about. You can call me at any when you have questions or just ask them on here, you'll get plenty of answers.
Remember too, Rome wasn't built in a day and those beautiful columns had a solid foundation under them.
