Need some help from you snow guys. I am bidding a total summer and winter package. The guy wants one price for everything and pay the same amount all twelve months. How do I bid for the snow removal and salting without knowing how much and how often to expect snow? The lawn care will run about $12,600 and I would hate to lose this by overpricing the snow removal. Thought about subbing it out, but would hate for it not to be done correctly and lose the account for something out of my control. Any help would be greatly appreciated.By the way, this is in Indiana
