Help Me Become A Certified Guide

Hi my name is Alison.
I have been doing walking tours of Camden over the last four years and I would like to become a certified guide by Camden Tour Guides Association.

I am raising money for the course fees, which is £850.

I need the money by September, 2016.
I love Camden and most of my tours are based around Camden.
It would mean everything for me to get certified and to receive a Camden Tour Guides Association badge.
I really want a tour guide badge!
