Looking for help from a talented team to redesign our current website http://www.cellularity.net/

My idea of the new website is to have the following tabs:
Home, Products, Store, Support, My Cellularity, About
Each of the above tabs/links would list the available product categorized by Mobile Platform. Example, BlackBerry, Android, Symbian, Windows Mobile. This is a lot similar to http://www.oracle.com/index.html

Home
List of products available with log splash screens

Products
List by Platform first then by product, similar to Oracle website

Store
Provides for a way to purchase our products

Support
The idea is to be similar to products but lists the support and knowledge base for the product.

My Cellularity
Work to be done in-house

Admin Panel
Need a simple and graphical interface to update the website contents and add new products to the website. NO WordPress please.

SEO
Please include Search Engine optimization in this quote. Including articles writing and linking and the expected ranking expected.
