I used to work for Tru Green 1982. We got great response -the first time--until we paid all the postage on the incoming cards and discoveredthat 65 of them were fake--bad addresses--and all with the same handwriting. After that we got about 1 percent and we did very well--but--there was hardly any competition at that time. Other comments are just my suggestions from reading marketing articles over the years.
After i started my own company, I did phone soliciting for two years and then used mostly referrals--free app for a sold referral--limit value of $50.
I also ran a contest--answer 6 local history questions and win free aps for a year. Ties determined by drawing. Limit value of $250. And fill out the referral information below; you are rewarded with a free ap if they become a new customer. Mail in your entry today.
