Have a look at the jobs on offer in your Local Authority's Education Service - you don't have to be a teacher to work for the Education Service but the experience would be useful, there are a number of different sections Education Welfare, Special Educational Needs, LAC Education Teams, etc
As froggequene says, you're well qualified to work within the LEA, even if it's not as a teacher. With your experience, you'd be great as a school secretary, I'd imagine. If you specialise in a subject, I'd think you could advertise your services as a private tutor, or maybe get a childcare qualification and work as a nanny, or in a nursery or childrens' club. If you want to get right away from that sort of stuff, perhaps you could train as a social worker, or counsellor? Best of luck.
