The help I need is in finding people who need to use my English teaching skills! I am a qualified and experienced English teacher, happy to give English lessons; I have had experience teaching Business English. Also love to teach school learners. Private tuition in safe environment. TEFL trained, CRB checked. Experienced at teaching in UK. I can adapt lessons according to the need of the learner. Skype lessons are available too for housewives or mothers who stay at home looking after children but need to develop their English skills. Where can I advertise?

Have you ever thought about organizing some linguistic school, speaking clubs? I think this might be a good choice for you. And besides you can share your practical skills with other teacher and help them in selfimprovement.

I would suggest that you use you local paper and contact you area School AEA. They can post your information for parents needing tutors. Also contact your local colleges, Libraries and learning centers in your area. You will find more help in getting your name out those these outlets than advertising itself. Not to mention you will have a safer clientele dealing with schools and learning center.
