Need to create a mobile friendly site

Hi,

I would like to create a mobile version of my site www.bonappetitcard.com. It'll have to have at least :

Buy membership
Restaurant pages
Search Nearby
Main Search Page, Terms & Conditions, Privacy Policy throughout
Flags for people to change the language or automatically change language based on the country the site is opened.

Please send me a message with some of the work you have done and your best proposal.

Regards
