Creare un Template per Wordpress - Repost - open to bidding

Hello, I need to develop a simple wp website that manage some point of interest on a Google Map. In particular, you must design a custom post type (POI), with coordinates of () category of the point of interest (drop down) and additional textual information. The fields have to be implemented with the module ACF. For the frontend without using ready-made modules, you will have to make maps that contain points of interest with its categorization of the marker according to the specified category. Via a script in javascript (jQuery) you will be able to filter the markers according to the selection of a checkbox (ajax). The map can be recalled through a snippet or dedicated shortcode. It requires clarity in the writing of code, comments in the code and documentation. Your code must be understood and extended in the future.
