Hello, I work as a freelance developing websites, mobiles and desktop apps. I have worked on similar projects previously so I can do your project. I can create a script in PHP to crawl the data you need. I can also use the Google API to retrieve the geolocation of the addresses crawled. If they are well-formed, I will get their latitude and longitude. An Excel file, with all these data, will be created every time you run the script.
If you have any comment, just contact me.
Best regards,
