i volunteer for a goverment organisation that works with children under 4, they are paying for me to do some training which will enable me to facilitate a group working with mums experiancing post natal depression.now the people who normally facilitate these groups do so as part of their job description ie health visitors, social workers etc as i am a vol i will do the first course for free but if it is repeated or if it goes to another borough i will want to be paid.so a/ why would they use me as an independant facilitator and b/ how much would i charge? it is one day a week over fourteen weeks. any advice would be great.
