copywriting for eCommerce

I need to have someone to do the descriptions and main page for a onlline decal store. I would only be able to provide the type of products we use so for descriptions of the quality and use and longevity of the products these would need to be obtained from the product website. I suppose other ideas could be obtained from competetor websites. I will at sometime be offering well over 6000 different decals so I would need multi use description template so I would like 30-40 different short product descriptions that could randomly be used on all the products.
