My brother and I are rather new to the lawn care business. We are in the process of submitting bids and can't agree on what rating system to use. My brother says that we need to submit both an hourly rate and a flat rate for each time we cut, trim, etc. I think that we should just put the flat rate for each time we cut. Also, is it better to mail the bids or hand deliver them to the receptionists at the business?
