Content and product descriptions for LED lighting products

I have a website where I market LED lighting products. My products are LED Street Lights, LED Bay Lights, LED Flood lights, LED Landscape lights, etc. Basically this job will involve rewriting all my content on the website, and also helping create informative spec sheets for the products. This job will only be offered to someone with experience with my field. Also I would like to have Press release's and email campaigns on a weekly basis. This will be on going work.
