Good luck to you. Sounds like you're not prepared to open a business yet or at least take on commercial accounts. As for picking up trash? Did you ASK the own if that's what he wants done each visit? Did you go over everything with him while you were there? Only YOU can put your numbers together for what the customer wants done. Nobody can give you a price. For one, none of us are there to see and talk to the owner to see what exactly they want done. A hint, time is money.
