Travel Portal + GPS Navigation

We need a develope of a Web site of travels this is a resume of our requirement A great summary would be: We require that the search made by the navigator is made on the GDS's ( Sabre , Amadeus, Galileo, Travelport, Tourico, Hotel beds ) and on the Data Base of the "Local Supply" (data base offers products and services It is managed locally in the administrative panel. Packages, Services, Products, Hotels, Shows, etc) , The results of the search are displayed to the buyer depending on some business rules (eg: Show first "Local Supply", then the Results form Sabre GDS, then Galileo GDS). While the buyer selects your flight or hotel or package to the destination, the system show the products and services related to that destination (shows, restaurants, hotels, etc..). The buyer selects (He can filter the results according to some criteria) products and / or services that he want (adding to a shopping cart) and make payments online (Integration with payment gateways) once payment is made online should be reported to the GDS and the "local supply" database of the purchase, issue invoices and bind to the CRM module. The site will have different sites relating whit different brand and graphic design, but whit the same functionality (independent agents), so that all purchases must identify which site was conducted. Content pages of the site as "about us", "Help", etc will have a CMS content management sistem for updating and maintenance. The site will have a banner administration system. When the buyer is identified, the system should be updating the profile of the buyer from his searches, products and or services he consult, destinations, etc. The entire site should be independent from the graphic design and function (using CSS), must be the web are recharged via AJAX, and validation of the forms must be done with Javascript (JQuery preferably) must be programmed in PHP 5, and use either any DBMS ( MySQL, MSSQL, Postgres).
