Depending on what level of service you are after, my mate Hadleigh who has restored my 1200 sedan previously, and also my current project 1200 coupe (click on my signature for links to build threads/ progress photos etc)
He could be interested in undertaking your work, depending on your budget, what you require, and timing (he is usually booked out for several months in advance with clients waiting to get their cars in)
He is currently doing a bare metal build up of a left hook 240Z amongst other classic cars.
his contact details, are on his (basic) web site:

If you want to do a road trip down to Timaru at some stage with your Z, and see his work first hand, and maybe check out the Z he is doing, and view his work to date on my coupe I can tee this up for you.
Cheers
