1994 antifreeze leak

im working an a 1994 jetta w/ the 2.0L 5 speed. Its leaking anti-freeze, around the lower radiator hose. it doesnt appear as if the hose is leaking, however the power steering hose directly below it how alot of antifreeze on it. is it common for the radiator to be leaking right below the lower hose? thats about the only spot it looks like its coming from. anyway to fix the radiator? and how do i test it since, i personally havent seen it leak, but you can see that it certainly has been.
so if i fix it, how much should i charge, assuming it's actually is the radiator.
any help is greatly appreciated.
thanks
