If you are new to flying in general going big is a bad decision much better off spending the cash on some quality starter gear. Transmitter/controller will run ballpark $200 for something pretty good, goggles easily can cost $600 if only plan to do line of sight flying or GPS controlled then could be a non-issue but if plan to do manual/FPV flight of the quad then is just about mandatory especially when talking spending nearly 1K on the quad which if crashed hard would likely be a somewhat major loss. Good controller/goggles can last and be used across many models of quads but would suggest if beginner do some research on those parts and get them first, then using any simulator/game (velocidrone/lift-off, DRL etc) is a good way to get used to controlling things in the air before actually jumping to trying to control things in the air but also getting a 3" quad (prop size) is good for beginners so they can learn to fly on something durable. As the saying goes the bigger they are the harder they fall.
Assuming already have transmitter/goggles then the quad itself could probably be built somewhere in that ballpark, but depends on getting a deal on motors and batteries and under load I wouldn't expect anything that can fly for that long honestly (not without being a human size vehicle/carrying a massive battery). ecalc.ch good site/resource if want to run some rough numbers with weight/dimensions of things you're thinking then can check out component costs but isn't a super easy ask
