Since money doesn’t matter, and you have an unlimited budget, you should purchase an AVID Adrenline HD system running on a HP xw8200 computer, with about 2.5 Terabytes of storage. This is what most TV stations use today, and it will do HD that is accepted by every TV station, as well as Standard def. You can also get Adobe Production Studio that has Adobe After Effects, Photoshop, Illustratior, etc. If you need audio, get a Pro Tools system -a small system like an 002 which runs Pro Tools LE will work just fine for you.
There are many variables, and they are all based on price. If price is no issue for you, get the above equipment, and you will be very happy.
