If you were teacher in UK would u use an agency or not?

[lynx]

Hello,
I am a music teacher qualified for England,for first time in UK with no experience in here,originaly from Romania.
Could this be better for me to use an agency or to look for a school?
I dont have NINO,CRB or self-employed(work permit) yet.
If tried to reach schools directly and they say to me I need CRB for having access in school.I told them I dont have it yet as I dont have an employer(school or agency)to do it for me.
I tried to get NINO card.I was answered I need an employer to apply for me.
I tried with self-employed.They notified me I first need to start work and after I need to apply for self-employed!
I have 2 bank accounts,stable adress,passaport,drivers licence as another ID,England qualification.
I dont longer know where to start,and who to talk to!
I need an wise advice from you.

Thanks
