I have chance to do lawn maintenance for a chain of gas stations- 10 total- I'm also thinking of buying a powerwashing business- turn key operation- trailer, and steam cleaner. Thinking about offering a contract to gas company for powerwashing pavement on a monthly basis. Does any body have any input on commercial powerwashing. Ex. pricing? The reason I'm thinking of adding the business is 1. I think I can get the contrat and 2. My employees are mainly hispanic base who want as many hours as they can get.- They can do the powerwashing morning and nights when places are closed or not busy.
