electrical schematic

I am looking to hire a freelancer that has experience in creating electrical schematics. Specifically, I need a wiring diagram for a specific model or system. The complexity of the schematic is basic, and I am looking for someone who can deliver accurate and timely results. As this is a technical project, I require a freelancer who is highly knowledgeable and experienced in the field of electrical engineering. I am open to suggestions as to how best to approach this project, and look forward to finding a freelancer who understands my needs.
The attached file is old version and needs updated for each schematic and created in seperate files. I can provide all the details . These are used in Equipment Manuals and created by a previous owner, I have no file other than one attached.
