Install third party ROI tracking code into Magento Store

We are listing our products on [login to view URL], [login to view URL], [login to view URL], [login to view URL], [login to view URL], [login to view URL], and pronto.com. We need to have the advanced tracking code they provide added to our Magento store with the correct reporting variables. In addition to the shopping ROI tracking codes, we need to add Clicksor tracking code to the same location. All tracking codes needs to be added to the successful order confirmation page. Due to modification made by third parties and one page check out, it looks like getting the code placed is more than just placing in on the success.phtml. We will be able to provide all code from the sites above with our correct ids and help with testing. This work will be done in a live store.
