Looking for a Google Pay Per Click Set Up & Management Company

We are a small Limo company looking to increase our website presence via Google PPC. We need an experienced PPC company to prepare and manage the Google PPC on behalf of us. We would like to work with a professional company who can show us performance and improvements. This first project will be a trial. So the company which will take the job and run it successfully throughout the given period, would have the priority in the next phases. Since this is a small business I cannot risk working with new providers with 0 feedback or feedback not related to PPC / adwords. If you don't have previous experience or feedback related to this field please don't bother bidding. Experienced PPC professionals please send us your proposals.
