Logo Design - Recommendations?

Hi all,

I'm looking to get a variant made of a current company logo, with a small change to wording and colour scheme. I have the original (in .eps/jpg/pdf) and a fantastic MS Paint design of what I want.

As the original designer is no longer in business, does anyone have recommendations for a company/individual that could do a good job for a fair price? Preferably NZ based because economy.
