My advice as a full time employee who contracts.

Option 1: Don't get a gst number until you hit 30k. To remove a gst number is a lot harder than getting one.

Option 2: Incorporate and get your gst immediately. Advantage if you are buying materials.

Option 3: Get your gst and do not incorporate. Lowest tax rate/highest cost for taxes.

Knowing when your contract is to end should help you decide. In your case I would incoporate immediately if the contract is > 6 months.
