Need assistance with Advanced Adwords\Google Analytics js Configuration. LIVE assistance via IM\Skype required

I need you to correctly integrate my Website with Google analytics tracking javascript code so that I will be able to Connect my ADWORDS campaign details with GOOGLE ANALYTICS. The problem you need to solve - at present the website is using a 3rd party Payment Gateway - www.plimus.com. And I'm not able to track down the exact Keword used in ADWORDS campaign that led to the conversion. This project requires TIGHT communication with me via IM or Skype. AFTER I accept the coder for the task. ## Deliverables My project website has Google analytics already running. I also run Google Adwords Campaign. But for the reason that I'm using a 3rd party Payment Gateway - [login to view URL], all the information about the exact kewords that led to 2 conversions types: 1. Software Demo Download. 2. Software Order. Have been lost. Your task is to is to help me integrate Google Analytics script with both - my website and the payment gateway - so that I will be able to see the information about the both named conversion and MOST IMPORTANTLY - the exact keywords that caused the transactions. I will give access to both my website and the Gateway Cabinet after I will accept your bid. I can fully modify my website code (in PHP\MySQL). And I have some control over the Payment Gateway pages HTML. Please bid only if you have experience in 3rd party cart GA interaction configuration. I will answer your questions in most detailed way.
