Nem/Coral lighting on 90g?

Anyone able to put me in the right direction for lighting on a 90g before I make the jump into BTA and corals? Thinking of going LED. Currently have T5HO on my 30g that's FOWLR. Great so far. As far as what will be in my 90g, starting off easy at first, mushrooms, zoas, etc. and eventually one day down the road jumping up to harder (care) corals. Don't really want to spend more than $400-$500 but if need be will just wait until I can get the right lighting.

thanks in advance
