Meta Tags/Seo and Category Descriptions Filled in

I have attached a sample excel file of columns A-G. Columns A, B, D and F are basically already done. You will focus on completing Columns C, E and G which are the Category Description for that page, a meta-tag description that will be based off the Category Description and a list of keywords followed by commas. As you can see some of the cells in Columns C, E and G are filled in already. You will not modify these at all. I will give you three competitor websites that have these pages descriptions and meta tag descriptions. You can use these pages for research but most of the work will involve simple rewording of words. I ask that you send me a PMB with your bid showing me how you would fill out the Category Description, Meta Tag Description and Keywords for a website page with "HTC HD7 Accessories" and another website page "HTC HD7 Car Chargers & Data Cables". My only rule is that you must have unique content on everything. I do not want duplicate descriptions or meta tags. I will be happy to assist you in the first several ones so you have an understanding of what exactly we are looking for. Also very important, the Meta Tag Descriptions Cannot be longer than 255 characters! Based on my work experience I am estimating this job will require approximately 100 hours to complete. The work is very easy and repetitive. Should the work end up taking longer I will compensate you the additional work through a new milestone payment.
