Web app to publish geo-info (Wordpress)

The app to be developed should enable authors to publish and edit information about themselves plus their resp. location on the web, if possible in a Wordpress environment. 1. Author administration/input and storage/ data administration: - We provide xml files with author info and related content (location infos) - Import this file to a MYSQL database (creating appropriate relations of tables) - Import and or link/relate other tables in MYSQL (Wordpress author tables) on same host - develop a backend UI where users can post and later edit their content - if possible this UI should be based/related on/to or use user administration tools/tables of Wordpress - if possible the UI and its forms should be based on a WP plugin like Gravityforms/Formidable ( we want to change and customize it easily and by our own) - install google or other maps plugin and relate this with all addresses/geo info within the database 2. Output, frontend UI for end users : - the starting and front page is highlighting variuos locations by selecting lists of the posts/user gererated content - if possible output should be implemented in Wordpress page (iframe, included PHP or forms pugin) - users will search content for variuos indexes and full text search - users wil find content by navigating on a map - respective lists and details of selected should be displayed in or as Wordpress pages - design can be provided as PSD both for desktop and mobile browsing (if possible using standard mobile plugins for Wordpress) 3. This web app - in a further Freelancer.com project - should be easily developped to a IOS and android app using the apps architecture of data input, UI, design. NOTE: Providers should have experience with geo-information and are invited to propose also own ideas to implement the project efficiently. If you can develop also the PSD design we will define an extra design project for you here, when we know which screens we need.
