I think you will find that the information that cleaning companies give to prospctive customers is to most, the key to get the sale. You would get a copy of mine out of my dead hand! I have been evolving mine for near on 3 years now and I am still adding. Surely you have a start place from when you were working for someone else or intercepted a competitors?
To get you started think about who you are, why they should choose you, what assurances you give, training, H&S etc etc
