So far I have been mailing them out to contacts I bought from directmailtools.com
I chose mailing them because last time I hung out door hangers it was the heat of summer and it sucked ***. paying 38 cents (6 cents card cost 4 cent contact cost and 28 cents delivery) per customer contact was worth it to me when compared to schlepping around in the Florida summer heat.
Coming up on the spring I'm going to hire a couple of guys to take out with me and just manually hang them on doors through the neighborhoods I want to work in.
the mail list is all well and good but I figure I can distribute more per hour at a lower cost than mailing. Mailing is worth it when it's hot though...
