I am entering the insurance sales business...what is best place to find clients (other than business cards) ?

First of all let me say congratulations and let me also say I'm sorry. You are entering a wonderful industry and to even want to do so I believe you have a big heart and desire to help people already. Clients (including your friends) are about to become the most elusive people on the planet for you. In fact, I often joke (although it is true), when I do not want to talk to people I tell them I sell insurance. Not much else can clear a room faster than that.

Anyway, the absolute best way to generate new business is via a database and use that database to fish for referrals. Ok, you say, I'm new and I don't have a database. That's fine, in fact, you have a edge because of it. So, I will share with you an effective "script" I've used to create a database.
First of all, because you are new you will need to speak with someone, I don't care who, but it's usually best to start with someone who you already know, and that likes and or trusts you. Let me also say, your goal is not to earn the business of the person you are in front of, it is to access their database of people. So here is the simple script.

At the end of ANY conversation:

Oh, <name>, by the way, if you were in the market for <type of insurance product here> or had a friend of family member who was, do you have an <insert job title here> that you would refer them to?

If yes, great then move on.
If no...

Well I know this may seem a little odd or weird, but I'm wondering if you'd be open to the idea of us developing a relationship on that level?

If no, say ok thank, then move on.
If yes...

Awesome. When you are developing referral relationships what is usually the way you go about it?

(Now normally most people don't know how to answer this question, and that's ok. They will often respond with something like, well I don't know, if/when you see them struggling to answer then say this)

Well, do you think it would make any sense for us to sit down and I can show you what I do exactly, you can bring your phone book / database / cell phone, and we can talk more about it?

If no, then ask, really, why not?
If yes, then ask ask, really why?

No matter the answer you should be able to set an appointment.

When I do this I often get an appointment with the person I'm talking to and often their business and referrals.

I hope I've helped.
