Well if you already have figured out you want a reef, I suggest a little more research and you look into what sort of reef you would like, and how much money you are looking to spend.
You could have a softy reef, mixed reef, an sps reef, lps reef etc. The list goes on and on, but each have different requirements and needs.
Lighting, protein skimmers, livestock.. I suggest you do some more research before you dive right in. Nothing good ever happens quickly in reefs. Take your time
