One place to start is considering just why you're thinking of moving to Italy. First of all, do you speak Italian? If not, you probably should work on that first.

Right now is probably not the best time to be looking for a job overseas unless you have ties or experience you can fall back on. Start researching the job market in Italy (which will require you to understand Italian) to see where your areas of greatest opportunity are. You can start by finding Italian business newspapers and magazines online and see what they offer for job postings. (They will also probably have some articles about job prospects and specialties in demand.)

Not all professions or areas of expertise are in demand in all parts of Italy (or any country) and your job hunt may wind up determining the area you need to live in to pursue your chosen career.
