Simple geolocalisation page - API change to google map

As a reminder here is the description of the project (completed already). What we require is that instead of using using OpenStreet , we migrate the code to use Google maps instead (with google maps api). Please pay ATTENTION to the FOLLOWING , your bid will be dismissed otherwise. This is a code migration, code cleanup in essence of ONE file (one script in essence). The project files etc are done. It works as intended. We would like to migrate the code to use google maps instead, thats it. Description of project (everything below is completed and is here for reference). I am looking to have the 2 following pages done. Technologies to use: php + mysql (geolocation api from google) Page 1: as per screenshot provided: details of geolocation of a scooter (4 scooters max tracked) scooter 1 | geolocation X,Y | Driver: Sam | Batterie level: xy% | Alert (green or red) Map with locations connected with a line. Red dot if alert at location with message. Seach field allows the filter per scooter date, display locations accordingly in the map. About the data: one table on mysql containing Scooter number (int) | Date-time (date with time)| Geolocation | DriverName (string) | Battery level long | Alert (boolean) Page 2: simulation page contains a form to feed the data above to the database. When Page 1 is refreshed, reload the data. If you have read this description and have experience using php / google map api / htmp / javascript, you can send me a chat request with an estimate on time to deliver.
