Best advice I could give is to knock on doors. When I was first starting out I couldn't even get an interview, let alone a job, and that was with a degree in graphic design.
I got so fed up with this that I booked a hotel in London for 2 days and just knocked on doors asking if I could show my portfolio and if they had any work experience. My persistence and cheek landed me experience at a major agency. I worked for nothing but my travel expenses, and was offered a job just over a month later.
Email and calling only go so far. If you want real results, try to deal with someone face to face.
Hope that helps.
