compare website

I am looking to outsource the development of our flagship comparison site. my new project which is a comparison site like [login to view URL] (but with a difference even i enclosed different site reference document) with base on product feed information(API/XML) and manual intergration. The site needs to be designed to reflect the brand. Required features:- We would like to list all the products that we deal with and when the customer clicks on apply etc they will be redirected to the affiliates that we deal with. We cover products like Shopping, credit cards, flights, Broadband, Internet, bank accounts, Insurance, Travel, Mobiles and loans etc. They will be put into sections and then go to pages where it will list them. We also need a backend CMS where we can add products and links to sites etc. Also we Need CMS suggestion - maybe database driven? So I can have database of offers from feeds? (at least for shopping) Thinking Wordpress with Pages listing affiliate offers? Or Joomla with wordpress for articles. Open to suggestions. Need link management system to generate and track outbound links and have keyword friendly SEO urls so I can includes links to any offer in emails, facebook: SEO friendly pages like /credit-cards/ Outbound links redirects to affiliate links Especially for the shopping section, I would like links for each product in the merchant feeds so we can email customers links in newsletters. Have heard of samurai/ninja link cloaker, suggestions? Overall you can say that I would like to make a site similar to moneysupermarket dot com or any other listing site(i enclosed site reference website). Also we need a ADMIN panel which can allow me to edit/delete listings, users, passwords, contact users, upgrade users, set payment gateways, change fees. I will also need a way to add/delete states, and other listing info.
