Amazonflex block catcher script

I am looking for someone to build a script to pick up Amazon Flex Blocks. I want to build a script similar to [login to view URL] which enables people to sign up, add their amazon account and the website helps them in grabbing the amazon blocks they want depending on their preference . If this is something you can work on, You can check out [login to view URL] to see how the site works, and that's the exact type of site/script i want any professional that can build it to work on.
