Product insertion in Online Store

The job consists in inserting products in a prestashop platform, which is the same as any other ecommerce platform.

It's a simple copy paste job when it regards to the product itself and description, price, adding pictures, but some of them will have different atributes like sizes, colors, material, etc.
Some of the products will wave as aswell youtube embed video links to be added, and links forwarding to reviews and communities.

I've calculated the time, and it takes about 90 seconds to add a product, in average, considering there will be products that will take 30 seconds to add, and others will take 120 seconds. I'm considering the "pauses" between products.
I will base this in a 20$ hour rate, which gives a 40 products per hour, and 0,50$ per product.
That's what I'm willing to pay. Payment with paypal.

I have 500 products to begin with, all of them in the aftermarket car parts, mostly of japanese manufacturing.
