Wiring loom mayhem

Hi can anyone suggest somebody who can help me with my wiring loom, I bought the car with no interior just lots of wires

If you can work to a wiring diagram it's not over complicated, however most looms have been butchered so badly over the years you're on a hiding to nothing from the start.
I've always believed the best way was to start with a new loom and take your time, basically one wire at a time. it's time consuming but will be for anybody and therefore can be bloody expensive if you take it into a garage
