I don't know how such a business can even exist these days.
Unless you're really trying to level up your photography to something in the top .01% of photographers and learn complex studio lighting techniques, you can learn everything, quite easily from Beginner Braindead to Advanced Ace on YouTube. It's all Free, sponsored by big US camera retailers and is explained by celebrity photographers.
I tried to go out hands on with someone once and explain DSLR photography to them and at the end of it, I said "just go on YouTube, it's the same crap I'm telling you, only you can rewind it as much as you like"
