as others have said, earning 300-350 per day sounds great, but you need to factor in any "perks" your fulltime job has that contracting can't offer - pension contributions (start making your own) hardware (buy your own machine + software etc), training, paid holidays etc.
You will also find that some contracts are working on fucked projects where contractors are hired as a last resort/scapegoat and the work will be "get this done fast" rather than any quality product being delivered. Not saying it's all like that, but prepared to be jaded if you do this long term
