You get the drift. So, I want to be proved wrong and shown that a 5-20 gallon tank can hold fish, and cost relatively the same as a similar sized freshwater tank. P.S. I may end up stealing the idea.

Sorry to break it to you, but a fresh water tank won't even be close to the same price as a salt water tank.
Buying cheap dry rock will cost about $3 a pound. For a salt water tank thats $250 in rock alone if you go for the low amount of rock at 1lb per gallon.
, testing equipment, refractometer, heater is gonna cost another $175ish on the cheap end
Substrate will be another $80 if you buy the cheaper stuff from Marco rocks.
A box of salt is gonna run $40 - $50
Powerheads are gonna cost another $100 ish depending on brand.
A used tank, stand, and light could be bought for another $200 or so on craigslist
