Google ad word,SEO campaign agency manager

My business needs a skilled agency manager of Search Engine Optimization and Pay-Per-Click Advertising campaigns. I have no existing keyword list or budget for this project, so I'm looking for an experienced manager to evaluate my needs, design a strategy, and manage the campaigns. You will be responsible for setting up the campaigns, managing them on an ongoing basis, and optimizing the performance to ensure maximum exposure and receive the best ROI. I'm looking for an expert who can demonstrate yield from previous campaigns and provide a road map on how to maximize returns. I'm open to creative ideas and tactics to ensure the campaigns are successful.
