Urgent VISA renewal needed

Hi,

I was recruited in Toronto to work as a Teacher here in London. I have been teaching here for the last 4 years. Recently, I have changed jobs. This employer neglected to complete my VISA documents on time. Now I have a job but can't work because I don't have a VISA. Worldbridge said that it would take 2-3 months to renew my it. I can't possibly survive without a salary for 2-3 months.

Does anyone have any suggestions on how to get my VISA renewed urgently?
