What have you done to get a job thus far. Are you being pro-active and approaching companies and individuals directly. I've always found that the direct approach is best. Waiting for ads to appear in the paper and going through recruitment firms will get you nowhere, particularly in tough economic times.
What field do you want to get into.
A masters degree won't help you. Companies that put you on will do so as a graduate.....without any practical work experience you are not much value initially anyway, they will need to train you, therefore a masters degree is worthless at this stage.
