I want an example of a simple contract proposal for Cleaning service?

I am not sure if you are looking for residential or commercial, but you can find one at Start Your Own Small Business With Professional Business Forms And Support - Office Cleaning Bid Proposal if you are looking at one for offices and Start Your Own Small Business With Professional Business Forms And Support - House Cleaning Service Agreement if you are looking for residential.

You can also use the 'search' box at the top of your thread for some other good info...
