Develop a Mac Application

Currently I have created a multi-vendor marketplace by using wordpress- Woocommerce and the Dokan plugin. But I need more functions as below: -Customers can search the products by google map, when the customers type the keywords like "iphone 5" in the search form, it show all the related products on the google map, and it also shows more details information when you click on the spot on the map, such as, photos, prices, review or link etc for this item. -Our vendors need put the full address for each individual product when they list and sell them, I have bought the "geolocation my wp" plugin and the vendors can see the address field already, you may need to link the address field into the google API to get the functions above. -The listed products on the google map will show another list on the side with more details information about the product such as condition, qty, photos, reviews, and more. I have found some useful google map API to get this function, please go to the below link to view the example store, it is a store for all the restaurants in the world, but our website is included all the products and services with multi sellers in Australia. [login to view URL] I have also found the API you need to get these functions on below: [login to view URL] I will be great if you can modify the example API codes and save your time. Please let us know if the budget is not enough as we don't have the experience for the coding work. Thank you! Best regards, Tony
