Hi Paul,
There are not too many businesses you could start with that sort of money.
An EBAY, cleaning, painting or very basic gardening business come to mind but without more money, you will both need to be an expert in your field as well as be an expert in being able to attract customers.
To give you an idea, a decent website will cost between $2k-$10K. An ad budget can be $500 per month an upwards etc.
Be on the lookout for a lot of salespeople who will tell you that you can make money from a $2K business – most of them promise a lot but do not deliver.
Doing a small business course at TAFE or similar would be the best use of you time until you are able to formulate a plan that has a good chance of succeeding.
Cheers
