Add products to my website

Need someone or preferably a team to add products to a WooCommerce website. Product data must be pulled by hand from multiple websites and imported into my website using excel file format. Product type along with data type needed can be seen at gameware.com. Initially there will be a lump sum of several hundred to several thousand products that need to be added. Then on an ongoing basis there will be an estimated 30 to 50 products to add monthly. (Higher during the fall season when many games are released) Someone with some video game knowledge is preferred but not required.
