Single Webpage with Google Maps API

I am looking for someone experienced in PHP and Google Maps API to provide a standalone webpage allows me to do the following. Preferably someone who has already worked on this specific task or similar applications using Google Maps: - upload a pre-defined Excel File with 20 columns (approx. 5.000 data entries) - visualize with a colored dot (blue) a specified Address 1 (provided in 3 columns in the file: Country, City, Address) in Google Maps … Each dataset/line in the excel file has one Address 2 - visualize with a colored dot (red) a specified Address 2 (provided in 3 columns in the file: Country, City, Address) in Google Maps … Each dataset/line in the excel file has one Address 2 - … this way 10.000 data points/dots (5.000 blue and 5.000 red) should show up on the Google Maps in the page - A window/menu on the page (see example screenshot) allows filtering values from 11 of the 20 columns - When uploading the Excel File all selectors should be activated in order to allow visualization of all data points/dots - Users can select or unselect any or various of the values in each filter, for example: - BRANCH: Initially shows all branches selected and shows the dots for all datasets (lines in the Excel File) - BRANCH: If User unselects “Branch1” only the dots (Address 1 and Address 2) for datasets (lines in the Excel File) that are selected will be shown … datasets with “Branch 1” will not be shown (neither Address 1 nor Address 2) - One separate selector will allow to turn on or off the visualization of all blue or all red dots – this way allowing to: - Either show Address 1 AND Address 2 - Or only show Address 1, - Or only show Address 2. - If possible the export of this Excel File with 2 additional columns (Maps Latitude and Maps Longitude) is requested. Attached please find a sample screenshot of what I am looking for as well as an Excel File with the according structure we will use. Any questions – let me know. Best regards, Thomas.
