Thanks. Pruning is a very small part of my business, and I have always done it per request of the customer. Since I offer mowing, applications, mulch, etc it just seems to be the next step in going to full service(which is what I would like to do).
I've always billed it out per hour and told the customer a price range. I would like to try and include some type of pruning program into my monthly customers and trying to figure out the safest way to estimate without getting burned.
