I suppose you could look into a working holiday visa (if your under 25 I think the limit is, I may be wrong). That way you are not obliged to have a sponsor and can travel the country for upto one year and seek part time work to fund your stay (I am pretty sure I read it is only part time work your allowed to do on such a visa, that suits you perfect then). You could goto local schools, colleges while on your stay and hand in a cv for temp english work etc. Since your in the country and available for immediate start you could get part time temp work easily.
