I have read on this site about some people suggesting ways to start bidding commercial accounts. A few guys said to just submit a bid that is good for one year. I have a big list of commercials that I would like to maintain. Question is, what services do I bid? Should I just bid bush trimming, mulching, mowing, fert? Should I assume that they want all of these services or start with minimal services and mention that services can be added upon request?
