LG fridge/freezer 2 door not working?

My Lg approx 7 yrs old model no GR-L2-07NI just stoped working so the fridge nor the freezer is working. The light is on in the freezer, but in the fridge the light is cutting out along with the motor every second as the motor is trying to work. Can enyone tell me what could be wrong and is there a person who would come over and be willing to give me a free quote to repair it. I live in Boronia Hts 4124 Qld Australia or feel free to ring me 0400779088
