Travel photographers is becoming a thing but not in the way you think judging by your post. People are not going to fly out a photographer with them (unless they’re super rich, and even then it’s quite intrusive).

Instead what is happening is people are looking for local photographers in the destinations they visit more than used to happen. They’ll fly out to their destination and then find a local photographer. I did this myself this summer and absolutely loved it. It was so lovely and refreshing to hire someone else for a few hours to take photos of the whole family including me in a much more relaxed and different setting to what we’d get at home. The results were amazing, as it was a local who knew the area really well.

If you’re serious about doing this I’d suggest focussing on getting to know your local area, and what the best spots are in the eyes of a tourist, and become an expert at taking good photos there. You’re never going to get better results than a local pro just rocking up and taking photos. And the supply of people willing to fly you out will be tiny
