Slap up a sign with your pricing and services. Appearance means everything! Your customers are going to pull up at one of the nearby stores and see you and your setup and decide if they want to, take a chance. I suggest your signage is large enough for them to see the pricing without having to come to you. When things are slow, make sure your nice looking washed and waxed vehicle is parked out front and you appear to be finishing it up.
