Affiliate Page / Integration for GeniusLink

I would like to build in affiliate marketing into an existing webpage being driven by Geniuslink. For example, integrate a "buy it now" link on various game pages. (e.g. you see a link to buy a game as you are reading the review) It should be integrating into Geniuslink so we can run other programs beyond Amazon. I need somebody who is familiar and can help me quickly accomplish this task. The site is GamingTrend.com I'd like to accomplish this soon. Here's the Geniuslink page: https://geniuslink.com/how-it-works/for-creators
