Searching for job

Help needed! I’m a foreigner student in Riga. I have been working in a Kebab shop for the past 2 and a half years… It was ok as a student's job but I am getting really tired and bored of that. Any information about any computer job where foreigners with a small knowledge of Latvian could work? Maybe some internet shops as they became very popular nowadays? Mostly I can understand the Latvian language - at least the topic but I definitely cannot speak in it. I’m a good guitar player and I can teach English as well. Any information if the youth centres are taking foreigners? Or should I make my own private lessons? I have good communication skills even without knowing the language. Please help! I’m really tired of that smell of the marinated chicken. :D
