Not sure what the availability is like at your age, but maybe join some skills camps? A nutritionist and trainer both sound like good ideas. I think paying a person is a waste of money if you can afford a ball return net(Amazon link: https://www.amazon.com/iC3-by-Airborne-Athletics-Basketball/dp/B00AXM2PJO). This way you can shoot around whenever you have spare time, instead of relying on the schedule of someone else. I wouldn't go crazy with the skill accessories if I were you tbh, just get shots up in your free time and practice whenever you can.

there are all sorts of guard you can buy

or just rig up some posts and netting alongside the neighbors fence

Shooting machines like The Gun or Dr. Dish are sizable investments. I don't know what your definition of expensive is, but if you go on their sites, they ask you to call for pricing, and that's a good indicator of how expensive this stuff can get. A similar machine on Amazon was priced at 5000 dollars, and I don't know how much cheaper it can get from there.

You can get something like this for about 600 dollars. Or one of those "ball catch" attachments for a basket will only be about 50 bucks.

I think just making a friend will be so much cheaper, more effective, and in the long run, more fulfilling than any of those options, though.
