i have a few questions about plowing. Is it to early to start asking around to commercial accounts if they will be accepting bids this season, i know peopl look around mid october. and how do you set it up to get paid up front, i have a service aggrement/ contract. I can see giving the a price for each time it snows. and also do you charge them once per storm or is it each time tyou drop the plow? thanks for the help.
