do it in smaller chunks
if you blew it out, and suddenly had 100 clients, and you could only service 10 per week, you would have a pissed off group.
Smaller, more often, targeted areas.
remember people need to see your msg more than1 time sometimes.
so hitting them 3+ times over a 6 weeks, would be good.
as for the flyers, I found a good take action now offer, is pretty good.
like TEXT LAWN to 70259 and get a free cutting works.......
