What about offering a service that involves designing their garden plot for them? You know, which would grow best in certain spots etc.
well I do offer design in the add, i think it expired and I never reran it.
but all I got was the same ol guy calling me to ask where I get my organic soil from. I told him i have my personal suplier and I can deliver it to him but he declined and went on to ask me about vegitable that grow this time of year, I guess I messed up when I put call if you have any questions in the ad.
