Help me with Marketing

I want to create a marketing plan which targets companies that are looking to complete medium size projects, but either a) are not thinking to outsource, or b) are apprehensive about outsourcing for various reasons. Once the companies are reached, we will use tools like freelancer.com to service those customers. More details will be provided in discussion. Please provide a comprehensive marketing proposal, and please provide as much detail as possible about your portfolio and qualifications.
