Understanding change of placement in section I after permenant exclusion?

My son is in year 7, EHCP and been permanently excluded.

He was in mainstream and I was trying to get a change of placement but the LA had not put the paperwork through in time and told me to wait. In which time he was PEX. I'm not appealing the PEX as it's pretty pointless, he lasted 10 weeks in Mainstream school.

Now the PEX has prompted a change of placement under section I. I have named a specialist, the LA are consulting on Parental preference. But they feel his needs can still be met in Mainstream and consulting with them.

Due to the PEX he is now educated outside of school and the LA have set him work online with a tutor online. Which obviously does not meet provision F. I also work full time and after next week I have zero childcare. I have complained to the director of children and suprise, nobody cares.

I have two questions with anyone that has been through this:
1.When the LA name a school that is not parental preference I have the right to appeal under SEN tribunal, this is currently a 9-12 month wait, is this triaged as more urgent as he is not in school? Also will the 'tutoring' remain in place whilst I appeal?
2.I have contacted every solicitor I possibly can to proceed with judicial review, can anyone recommend anyone that could take legal aid and has availability?

I actually have no idea what to do and I don't actually no how I'm going to keep my job. Anyone that's been through this experience and could share would be much appreciated, I can't find this situation online anywhere.O
