Looking for a Snowden

Hi i am searching for someone to create a Web based software. I was wondering if someone can make a bypass for hmac authentication. I have a backdoor bot for adidas.com. basically they set up a splash page only letting random people access to product page. Now what they have done is added a hmac cookie that can only be obtained if you're on product page thus blocking the backdoor bot i use. I need someone to either modify the php or python script to bypass hmac or develop a separate script to bypass or aquire hmac without actually going on the product page.

Please let me know
