Yeah, it's hilarious to me when I hear about a guy in your situation goes out and drops a ton of money on things like cameras and software and computers. If you're just starting out, just go to Wal- Mart and buy a cheap Canon or a Sony (even the cheap ones are pretty nice compared to just a few years ago and a lot of pretty inexpensive ones shoot HD). And depending on your computer, there are tons of inexpensive options for simple editing. It won't be the same as shooting with a Panasonic HVX and editing with Final Cut Pro or Avid on a tricked out Mac Pro, but if you're just starting out, you won't even know the difference anyway.
It's better to start small and upgrade as you go. Because you never know, you might find that you don't have as much time to shoot and edit as you thought you would or you might just not like it as much as you thought you would.
