Welcome to RS mate.
Best advice i could give is to NOT skimp on your skimmer. Do a lot of research and homework first so that you dont get led down the garden path liek i was. It is hard enough in Oz to get exactly what u need but it is possible.
Barrier Reef Aquariums is a good place to buy live rock and some good priced equipment. The guy, Ian, is quite approachable aswell.
