Accountant

I am a freelancer and I have taken on another freelancer to support me, and who will be working as a sole trader. He has never freelanced before and I need someone to sit down with him for an hour to explain everything he needs to know and what to do to give him a 101 about being a sole trader. Ideally I'm looking for someone based in South London - as close to Camberwell as possible so he can meet with the chosen person face to face. Or you would come to our work place (for which I will cover public transport costs in London).
