Data entry/price matching

I have a document that indicates how much I have to pay for a product, and I have a website that allows you to manage prices. I need to do some price matching with my competition out there. You will need to find cheaper prices then the other companies or find the closet price. Remember the prices cannot go lower then how much I buy the products for. Keep in mind that the prices also must be a little higher then how much I buy them(to make profit).
