It is a tuff market, I was out of work nearly a year after being made redundant even with 13 Years experience, MCSA, MCP's, Dip, Wide range of skills. In fact that's why we're off to Oz, been offered a job there!
My honest suggestion would be try smaller firms, Computer shops ect.. don't write a letter, Walk in and see the manager or MD. The reason this might work is because most people are too lazy to bother, it's easier to apply via job boards, social networking and email.... and an employer wants to see someone with get up and go!
