Implement store locator on wp website

I'd like to implement a store locator with a layout similar to : http://uk.louisvuitton.com/eng-gb/stores

Characteristics:
-Results and search bar should styled as the example but should be floating right not left
- I can assign categories to the different shops and add a special pointer per category if necessary
- I can filter by categories
- I can add multiple different maps to the same wp
- I can batch upload via a .csv file
- It should be easy to style via CSS
- it should be responsive
- I can easily upload a new point image

POS upload NOT necessary we will do it ourself
