Yes I think You can start right away as a freelancer if you think

• You have the right Technical Skill
• You can market your self both online and Offline
• You can take what ever the client throws at you.
• Confidence that never comes down.. Even if you are left out of work for more than a month

I can suggest you this way... Find a steady source of income first then get in to the freelancing... At time things may get very ugly and you have to face that situation...

All the best from my side
