Evelyn, PWG makes a good point. First you have to make the phone ring.
A sure fire way for you to generate interest and in turn close sales is to pound the pavement. If I was a restaurant owner with a tired interior and have been debating a change, you walking in and offering your service would be the motivation I need. Make sure you sell your service on the benefits to the restaurant owner (ie increased patronage). Some of the best places I eat (great food, excellent service, unpretentious pricing) are very tired looking. You'll have trouble convincing those owners of change because they are going to have the "why-fix-it--if-it-ain't-broke" mentality. They are also going to be reluctant to make dramatic change as people are funny and will stop going to an establishment if the experience changes. I was in the restaurant service business for awhile with PressurePros. Many of the owners are old school and their ego will not let them accept change.
