waterproof light snorkel/scuba gear (Everett)

Need a dive light or waterproof flashlight. Also Looking for anything from wetsuits for someone 5"10" and 5'6" to tanks, BCD's regulators, snorkel masks, fins, booties. Also a hookah tankless diving system. I need to do some work on the underside of my boat while it's in the water. Anything that might be able to help me get me started would be greatly appreciated!
