Complete Newb, project help

Hey Laser enthusiasts! i need some help and my knowledge of electronics is extremely low.

I'm trying to find a laser for some painting projects.

I need a laser that will project a single dot centered, and two rings, one at 12 inches and one at 24 inches. Preferably with US power supply and an on/off switch.

Any help would be greatly appreciated! this would solve 3 weeks of searching for a solution!
