in doing some research on parking lot sweeping i came accross www.mascosweepers.com they have a part on there site called"starting a sweeping buisness" if you change sweeping to pressure washing i think you will get a lot of good info from this site.
If this is not the type of info you like listed on this site just tell me so.
