you could join a local BNI club or start your own, although existing clubs probably already have an insurance agent on their panel and starting your own network club takes a lot of commitment and dedication (bni.com)
drive around to open houses on the weekend, go inside and give the agent on duty a cold bottle of water and a flyer and two or three business cards; ask if they already have a specific agent they refer buyers to when the buyer purchases a home; if no -- then give a short pitch -- if yes -- ask if they will keep you in mind as a backup insurance agent becuse you are super responsive and your insurance rates are great and yadda yadda yadda, then leave and drive to the next open house (make sure you get a business card from every agent you talk with)
