What we do is come to your house each week and clean up all the dog poop in the back yard. You get a nice clean yard every week. The first time we come we’ll thoroughly clean your yard and collect for the month in advance and any initial clean-up charge that may be due. After that first time we will we mail you an invoice each month along with a stamped, self-addressed envelope. All you have to do is write a check once a month and drop it in the mail so that it gets back to us by the due date. We’ll take care of everything else for you.
