I sell Contractors Insurance for roofers, electricians, plumbers, carpenters, etc. I sell general liability, workers comp., tool coverage, commercial auto, etc. Where and how can I find some good leads of contractors who need insurance or need to renew their current insurance?
There are a number of companies that sell business leads or mailing lists, most have Internet access for a monthly fee.
I've used this to extract businesses by SIC codes in a given area and then you apply your favorite marketing method: dial for dollars, targeted mailing, drop in and visit, whatever works for you.
Start x-dating, find good businesses to write, then write them; there you go, you now have the MBA course in agency building. Good luck.
