Drumbeat,
You have a few options.
1. Use your British nationality and get a working holiday visa, good for two six-month stints. You can start work immediately.
2. Use your degree to fulfill the requirements for a work visa, find an employer willing to hire you, and go for it. You can either interview in your home country with the few companies that recruit there, or you will have to fill your pockets with cash and come here (preferably in March) to get the best shot at being hired.
