Slight Sunshop Modifications / Repair & Keyword Research

Need the following modifications to my sunshop based website: 1. Social media icons added into header for facebook, twitter, youtube, and rss feed. 2. Newsletter opt-in form integrated into website. 3. "Search our store" functionality must be fixed. Randomly stopped working. 4. Keyword research done for an upcoming SEO campaign. Need you to provide a list of recommended keywords we should be targeting. I will need you to provide me with a comprehensive REPORT that shows the keywords, both long and short tail, their monthly local (USA) search volume, and some measure of the competitiveness. Thought should be put into intent behind each keyword 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. I can do that myself. 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 time. 5. "Add a product" page in the back end randomly stopped working. When you click add a product it takes you to a white blank screen. Need to have this fully functional. Please keep your bids low as possible as we already paid two other programmers to do this work that did not deliver and our budget is a bit burnt out at this point.
