Any of you guys bid and install big commercial irrigation jobs? For instance a new shopping center, mall, wal-mart, Target, etc. ? And for those who do these larger commercial installs, suppose you have a job that is a $50,000 or $100,000 job, what is a typical payment schedule? How much do you get for a down payment? Do you get progress payments? If so, how often. There is a big market for this where I live but not being familiar with commercial bids I am not very familiar with how to bid these.
