Hello to the people coming to this question a little late. According to my calculations, Lynne asked this question about two years ago. I imagine she already has her answers! hahaha
Anyhow, I'm Thomas Anthony with Facility Support Services and I'm going to leave a link here for anyone like me (coming to the party a little late). This link: Construction Clean Ups
will explain most of the aspects related to Commercial Cleaning Vendors working with the Construction Industry. It will also show a sample proposal bid for service with all the different services required.
The Construction Industry traditionally pays higher amounts for project work (floor & carpet care, windows and pressure washing etc.) than existing structure contracts. This is a good direction for a Commercial Cleaning Company. Good Luck with your bids!
