Adding Products to E-commerce Store

I'm looking for someone with basic HTML skills who can add products to my existing e-commerce store. To start I'm looking to add around 500 products. Most of the products are already added to the database, I just someone to tweak them: calculate the cost, input the image, input the shipping, add options is applicable and add the product to the recommmend category, I believe this is it, there maybe couple special options a product may have, but this is the main part. Thanks, Aaron Hu
