CA is right, if you want to print in metal, and not just plastic with some meta dust in it, your budget is much too low. It's not the size of the metal printer that's going to make it expensive it's the technology itself, and there are no sub $2000 printers that will print metal. Most printers can print metal filled plastics, but you might find that underwhelming.

Secondly, you will not find a large format resin printer, even if you did it would cost you over $2000 just for the resin to put in the printer.

Lastly, adding particles in filament (stone, metal, carbon fibre) will make it weaker and more brittle. The particles are effectively impurities in the plastic and make it weaker, the plastic doesn't bond to the particles the same way it does to itself. As far as print quality, all they really do is give you a more matte finish and erode your nozzle.
