Keyword Research

I need you to do keyword research for our online e-commerce store so that we know which keywords we should be targeting in our SEO campaign. I will need you to provide me with a comprehensive report that shows the keywords, both long and short tail, their search volume, some measure of the competitiveness. Thought should be put in to intent and a brief interview regarding our products should be had before keyword research begins. I'm not looking for someone to type our URL into Google Keywords tool and have google suggest keywords for us. This needs to go deeper than that and be more thorough as we cannot afford to waste any money targeting keywords that will not pay off for us. If you do not have extensive experience doing keyword research and cannot provide the reports and information requested in this job listing please do not apply and waste either of our times. Already paid to have someone do this once from freelancer.com and was dissatisfied at the obvious lack of effort put into their research. Please do not disappoint.
