Multiple Third-party APIs to Connect with Wordpress site for Affiliate Marketing

I have a dream. Help me build an awesome, automated "third-party" store. The goal is to create an all-inclusive affiliated e-commerce site that will connect to multiple sites that have API(key)s for affiliates such as Clickbank, Linkshare, Walmart, Udemy, etc. (the list is long - there are many). I wish to make site, the place to go to, the ultimate shopping site as an affiliate marketer. (Why should eBay and Amazon have all the business?). (Though not priorities right now: I wish to also include other vendors who wish to sell products and services on the site - this can be done through a plugin. Lastly, I need to promote the site.) The site has already been created in Wordpress which makes it easy for me to maintain (the name of the site is not important for now). I just need to know IF you can do the job and what exactly do propose to do, how long will you take (deadline please) and how much you will charge for what you plan to do. You will be asked to answer the following questions when submitting a proposal: How can you help me with my vision? Are you capable of API work so that a site like Clickbank, Walmart can connect to my site and thus, make a shopping site? Have you done this work before? Besides your Upwork profile, can you provide an examples?
