LOOKING FOR A SOLICITOR WITH PLANNING KNOWLEDGE PLEASE?

I am appealing for help with regard to finding a Solicitor who would be willing to help with the Stop the Warren Road Access Campaign for free please (I know it's a big ask)? It would be to advise on planning law and public footpath implications and perhaps send a few letters on our behalf to West Berkshire Council please. It could also be anonymous if required. Any help would be much appreciated. Thank you so much, Julie
