Lead generation using Craigslist real estate / foreclosures / investor leads

We require an online marketing expert who can help us find real estate investors to buy foreclosures and investment homes (with tenants in place) throughout North America. Perhaps by using Craigslist or any other means you can suggest.

Please let us know about your experience in this area and what you would your rates are.

If you could let us know how quickly you can commence work and provide your skype id for correspondance.

Thanks,
