Yeah, all the technology is easily accessible. It's just a matter of throwing some $$ and time at the project. Unfortunately it gets pretty expensive if you are planning on using goggles to fly with. If not you will be flying all line-of-sight which may be a challenge because of the drone's small size. You can't fly out that far before it becomes too small to see and control.
I would see if you have a hobby shop in your area that specializes in RC drones. You might be able to find some used transmitters, goggles, and drones at prices that will save you a lot from new. It gets expensive to build from scratch.
If you don't already fly you might want to learn on an inexpensive drone like a Tiny Whoop before moving on to a larger, more expensive drone. They will bind to your transmitter and you can learn to fly inside. https://www.tinywhoop.com
