Call Leads

I am looking to work with someone who can generate call leads. I have clients who offer various local services. They are plumbers,electricians, lawyers, etc I have call tracking numbers setup and I am willing to pay X$ per call. Please send me proposals of how you will generate the leads ie ranking for local keywords or Adwords etc Please note I will only pay for performance-that is you generate the leads at your cost and I pay you per call lead. If you can guarantee above the fold page one rankings for local keywords then I will consider your services but i will only pay when rankings are achieved. I look forward to building a profitable long term relationship with a business or individual.
