I am getting ready to bid on a new retirement center and need help. I have never bid on something this big before. 12 acres in all, 1 large residence 4 condo-like buildings. 2 long storage unit buildings for residents. There is a lot of landscaping on the property. She wants mowing, trimming, weeding of landscape areas, pruning of bushes, and fall clean-up. Hope that this gives everybody an idea of what the property is like. It is virtually a 12ac. condo community. What is the best way of pricing it. How many hours it would take per mowing? Pricing it per service as far as mowing - fall cleanup - pruning etc.etc.? Pricing it as one lump service? Thanks in advance. This site has been such a huge help.
