Shopify Location Coordinate Selector App For Personalized Products

Hi there! Currently I'm looking for someone who has experience in developing 3rd party Shopify apps. What I need: 1) embedding google maps and a search field on a product page with functionality allowing a customer to select a location by either: a) using a search field to bring up the location and coordinates on a map. b) dragging the map to select the coordinates. Example: click on this page [login to view URL] and pick your own coordinates (powered by google). This is the basic requirement and would be ok. Even better would it be if you could use these coordinates and display them automatically like it is with this shop (by clicking "set coordinates" below the popup map). Currently I'm using the app "Product Personalizer" but I'm open to switch if necessary. Please let me know if you can do it, how much it would cost and how fast you can deliver. Really looking forward to hearing from you! Best regards
