Looking for someone proficient in Python and automation to modify a bot

I'm looking to have a scraper modified. It's a fb photo scraper that scrapes photos off fb profiles and adds them in an excel doc in different tabs. Currently it scrapes photos but they're thumbnails so they're useless to me, I need full sized photos. My dev said it can't be done but I'm sure it's possible so if you know your thing just hmu. It's an ongoing job as I need plenty of other features added or different scrapers created so no amateurs/time wasters please!
