I'm just starting the lawn mowing biz and a business wants a bid on the lawn mowing and a weed control program. He had new grass installed last year so he's concerned about it coming up good w/o weekds or anything. I have no experience in applying weed control, let alone knowing how much to bid on it. What should I do here? I would like to mow it and sub out the weed and feed to Scotts or some other local outfit. Is that a practical way to go? How does liability work if the weed/feed place damages the lawn? I'm not looking to make any money on the weed/feed, just make it easier for the customer to pay his bills. Any advice?
