Theme edit CSS floating button (shopify, pagefly)

I am trying to do a CSS3 floating button on my website as shown here: [login to view URL] I can successfully install one button but I need two for my website. I am trying to do two buttons instead on one. I need: one button for a "customer service" that links to a contact us page and a second button for a "rewards" that links to a rewards page I need both buttons to have text as well. I need the job done within the next 2 hours. It should be simple. Also I am using Shopify/Pagefly and would like to work together on this via team viewer or something
