I really wouldn't bother until you have your licence (or at the very least passed both CPL and IR). The airlines have hundreds of applicants every week and most of these are binned. There is no point contacting an airline until you are qualified and available. Not one will offer you a job based on your word that you're a great pilot. Concentrate on the flying for now and worry about the job once you have your licence in your sticky mitt. Good luck.
