Art Workshop India

Hi,I am going to start Art Workshops for children in schools of London with this NGO.The NGO wants to pay me but have asked me to give them a quote as to how much I would like to charge them. I am confused if I should charge them hour-wise or aftr considering the other factors. I have been teaching in India for 3 years and now I have moved here and since I am fairly new in this country and have no experience here, I don’t know how much I should be charging them?I am going do all forms of Indian Art with 24 children in each class. Each class would go on for 60 minutes and also each class would have a different age group. What is Rooting on Android . Denver SEO Company .
