Yeah, its a hard slog at the start, but in the end its worth it.

First few requirements are:

1) Go to Dept Fair Trading, Register a name. This is the name you wish to trade as, ie. Joe's Mowing..
Cost $161.00

2) Go to a bank, and open a small business account, in the trading name you registered.

3) Speak to a chertified financial planner / accountant, well worth it.

If money is a problem, start up a small website, and run your business from there. E-commerce is cheap and a wonderful thing.
When it grows, you can expand with it.

Its a hard slog, but the pay offs are there...
These are the first few crucial steps, and makes you legally a business.

Cheers.
