Machine electric troubleshooting

I'm looking for an experienced technician to help with troubleshooting an industrial machinery with an electrical issue. I'm not sure of the specific problem, however the Machine is not functioning properly. I would prefer the freelancer to visit my location for an on-site troubleshooting and repair. The most important factor is that the issues needs to be fixed as quickly and efficiently as possible. Please let me know if you are available and can help.
