You sound rather as though you just have an axe to grind.
Nobody is going to go out of their way to help you secure a graduate level post. You need to seek out volunteering opportunities yourself, not suggest that some government agency find you one.
Apply to TA jobs, help in your local Primary listening to readers etc., look at Mentoring schemes, or set one up yourself. There are youth oriented scemes crying out for volunteers, and that will give you an in road. When the school needs a TA, they might think of you. When they then need a teacher, same thing.
Look at private schools, who tend to be less prescriptive.
Or if you really have tried all of that, look for jobs in another sector, but be aware that the competition is unlikely to be any less.
Realistically, you are possibly at a disadvantage because of the time that you have been out of work. You made the choices that you did, and it's unfortunate that the job market is what it is. You just have to do what you can.
