Backdoor Links -- 2

I buy sneakers but they tend to sell out fast due to people who get into the site before the release and aquire the specific size they want. This is called "Backdooring" in the sneaker world. I have a list of sites that will be releasing a shoe this upcoming saturday 12/19/15. I am looking for someone who can scrape these specifc sites for the Variants & PID of the specific shoe, figure out the size run, and create links for the sites that include the size of the shoe so that when i refresh the link the shoes are in my cart and i can checkout in a timely manner. Also if that cant be done for some sites i would like to know if scripts can be created so i can add the size to the cart by implimenting it and check out quickly. If you are interested in this project please get back to me since this is time sensitive. I have the list of sites, the name of the shoes & the corresponding ID that goes along with the shoe. Also if you have done this before in open to suggestions and ideas. Thank you!
