EKO 85" TV Picture Repair

My EKO model K85USW TV has sound but no picture. It has not been subjected to any troubleshooting yet. I'm looking for a professional TV repair technician who can diagnose and fix the issue. Please, no basic troubleshooting bids, I need a serious professional. I Have checked and parts are ready available. Either give a price for repair or work by the hour. Easy on what you choose If you can give an estimate that would be great. LOCATED SPRING FARM NSW 2570
