How to get a listing in 6 months or less in a new city?

Here's goes the most probably the most commonly asked questions. I recently moved to Jacksonville Fl close to the Mayo hospital, 15 mins from the beach. I want to get business started but need money coming in quickly, don't know anyone here but I've been talking to everyone I meet in the community we live while walking the doggies. I've seen many houses around the area sold and aware of many realtors in the area as well. I'm want to knock as many doors that I can but noticed many communities have no soliciting signs. Doesn't help being in a tight budget Doorknock, call expireds, follow up- I appreciate any tips about growing quickly before the bills drown me. Thank you.
