Customized Google analytics Configuration

We require a provider with proven expertise and experience specifically in customizing google analytics configuration for advanced tracking We are looking for a couple requirements to analyze a Google adwords campaign. First we require amending the GA tracking code to accommodate a second domain name to allow tracking in a single account. Secondly we want to run A/B split testing on 2 separate landing pages for that 2nd domain, therefore we'll need to set up an analytics "experiment". And finally, each landing page offers a downloadable resource through a web form and once completed a thank you page appears to confirm the download. We will require the googla adwords conversion code to be applied to each thank you page. In addition the analytics configuration should include goal and funnel visualization for both landing pages and all necessary tagging Landing pages and confirmation pages will be supplied as complete and functional, hosted on our server. Examples of similar type work is a requirement and providers not able to demonstrate similar examples will not be considered.
