business directory search iphone/android application

I am running a Business Directory web site. Web site is a database driven web site and i used Microsoft Access database. I want to create iphone/android/Ipad/Blackberry application or mobile web site. Mobile application will use the same database and I will supply database and necessary SQL queries which i used on the web site. I want very simple search feature. 1. Search Button (Home Page) a. Business name search (text field and dropdown menu for the states) b. Category search (text field and dropdown menu for the states) 2. Business name search displays business name, address, tel, fax, email, web 3. Category search displays business name, address, tel, fax, email, web of all businesses under this category 4. Add your business button (form which includes business name, contact person, tel, fax, email, web, address) 5. Contact Details button (displays company contact details and includes a contact form) I illustrated and attached all pages as jpeg files. (thease are only for the information purposes) Developers will advice and work on design, inclusions and colours. If you already worked on similar project, please send the link.
