I have been a tutor for the past 2 years after I quit my NQT post and I love it. I'm lucky to also do intervention at a school, plus I'm allowed to tutor in the library straight after school. That means I can see 15 pupils a week, plus a bit of group intervention during the day. Add it all up and account for a drop in income over the holidays and I earn just a couple of grand less than an NQT salary. Obviously with teaching the salary increases up the payscale and a tutor's salary has a ceiling with there being a limited number of hours available in the day to work, but the flexibility and reduced stress/hours make it a definite alternative in my opinion.
