TYPO3 plugin for radius search

We need a TYPO3 6.2 plugin for a radius search for our already finished customer projects. BACKEND CATEGORIES: + list of all categories with add/edit/remove functionality + a category is a simple text tag e.g. "store" or "restaurant", but different for every language PROJECTS: + list of all projects with the ability to add/edit/remove them + a project has following input-fields in backend: - name, - street - zipcode - city - country (drop-down list of a hardcoded list of countries) - category (from category list, multilanguage-support) - picture (upload jpg/png) - type (textarea, multilanguage-support) - description (textarea, multilanguage-support) + a project has latitude and longitude fields, that must be computed from street, zipcode, city and country fields by maybe using google maps places api FRONTEND + LIST AND MAP VIEW - displays a map on top of the page with all projects as markers inside. The initial location should be configurable in the backend. If you click on a marker a small overlay should appear with name, category, type and a small picture of the project - under the map there is the filter bar with a text-input where the user can type his location, a dropdown with 30 and 100 km radius to choose and a dropdown to select a category - under the filter bar there is a list of all projects which shows for each project the picture, the name, the category and a "show more" link to goto the detail page. The list should have a pagination if it holds more than 25 projects. + DETAIL VIEW - displays the picture on the top left side of the page - right beneath the picture there should be displayed in tabular form: category, type, name, zipcode city, country - under the picture at full width the description is displayed - go-back button should be available. Please ask if you need any additional information. Thank you!
