I need to make more money on this end of the business NOW! As of today I am applying granular Lesco fertilizer every 3 months and only charging once every 3 months. I would like to move my residential base to paying me monthly; say $19 per month for me to put down fertilizer or every 3 months. Do you think customers are willing to pay monthly for a quarterly service? *at this price Im estimating that I will be making $98 extra per customer per year, but this is not really a pricing question as much as it is a billing question.
