Flipper, you can apply fert in the state of GA, but you can not apply any form of herbicide. You will need to get your applicators lisence. If you get caught you may face a stiff fine. If you land the job with the hotel you may want to sub out the spraying to a company in your area. I think your idea is a good one about sending out cards to potental customers.
