I had a Farmers Agency for 9 years. There are several negitive comments made about them but the truth is, make a business plan, (I like Business Plan Pro) and make a one year plan and a five year plan. Resist the temptation to change marketing stratagies when they don't work right away. Knowing what I know about Farmers, get a good MGA and use them because Farmers can be unpredictable and cold to deal with. While I'm obviously not a Farmers fan, I did make a very good living from them. Good luck to you!
