Install Clickcease Code and Tracking Templates

I am about to subscribe to Clickcease and I need someone to install the appropriate code on the header of the checkout page and landing pages of my store, CMS OpenCart with Journal theme, as well as the tracking template on my Google Ads account. The Clickcease instructions are here: http://docs.clickcease.com/en/collections/146449-getting-started. Expertise in OpenCart, Google Ads and Google Merchant and ClickCease required.
