It's hard to get jobs when you're out of work. Whenever I've been in work I've found it pretty easy to get other job offers, but after I was made redundant at 50 no-one seemed interested. In the end I joined an agency and took whatever they offered, and then after a while the people I was working for (via the agency) wanted to employ me directly.
So my advice is that it can be worth taking anything, just to get into the workplace environment again, then look around.
