Apply speculatively to various different operators. It is rare that you see advertised vacancies, as they're easy to fill ,especially with a huge number of out of work pilots looking for a job to keep them ticking over. Get the addresses of companies you could see yourself working for, have a good cv and application letter and go for it! Thats how I got my job. They're not going to come knocking on your door. If you don't ask, you don't get.
Good luck in your search. Hope you find something you like.
