Which industry(s) to target in marketing?

A different approach is needed for established and existing business, as mentioned above by Luke. Yhey know the game already had 10 of you coming every year. They might want to take advantage of price savings on you time. They may have a bad relation with existing cleaner, But have no time to look for a new one. Feel them out. Ask alot of questions. Make a preposal you can agree to. As an idependant business person i can operate my business on 80 to 90 % of what the companies can offer and still make profit. Saves the business i work for money. I know that so what csn they do for me as thier supplier mentality.
