Hi Kelly
I am in a similar position to you. I'm also single and planning to work and travel abroad next year. South Africa is my first choice as I have recently spent over 18 months living there and doing volunteer work and I would really love to spend more time there. Unfortunately I can't afford to stay longer as a volunteer so I'm hoping to get a work permit as a maths and science teacher. I've already started to get my paperwork organised and I'm in touch with a couple of recruitment companies. Not sure how much help I can be but feel free to contact me with any questions.
