Urgent solicitor/barrister needed for Court Hearing 13th April

I am urgently looking for legal support/representation for a first hearing in a Child proceedings case brought by my soon to be ex husband. He filed a C100 and I responded with a C1A. We have both spoken to Cafcass and I believe they will be at the hearing. I had to do an FDA hearing with no representation last week whilst my ex had both solicitor and barrister. I have limited funds but am hoping to be able to find someone within my budget who can help me as I only have a few days to prepare for this hearing. Many thanks.
