Just a few thoughts that may help here:
When starting with dry rock and sand, some do cycle the rocks for several months, but I think most do not. An extended cycle like that can help minimize the "ugly phase" of a new tank started with dry rocks, but others suggest that your just delaying it.
If you start with good quality live rock, you can start your tank pretty much immediately without much of an initial nitrogen cycle, or an extended cycle, and largely you can avoid that ugly stage too.
If you're planning on using dry rock, you could get that going now in your tank as you're acquiring the rest of your gear. All you would need is your tank, your rocks, a heater, a small circ pump and saltwater. Some like to "black it out" by putting cardboard or similar over the glass panel to prevent ambient room light from hitting the rocks. Keep your tank lights off during this time too. You could let this run from about 1 to 3 or 6 months or even longer if you wanted to. This would be a good way to get a head start on your build even before you have all your equipment.
I hope that helps and good luck!
