Call your solicitor and ask them. They should have a solicitor's "Yellow Pages" and be able to give you a list of solicitors in the Essex area.
  Then phone around these and explain your situation and get someone who specialises in traffic. They may even recommend someone else. 
 A good solicitor with local knowledge will be able to give you a reasonable estimate of what to expect. 
 Wasn't Mr Butters was it Paul?
