What should I expect to pay to have my car re-wired?

If I were to hire it out, what should I expect to pay in labor to have my 1967 Dart GT Convertible completely re-wired? I see American Autowire has a well rated nice complete setup for about $900 - but what do you think we are talking about in labor? I would like some input from you folks before I start calling shops. Thank you in advance.
