Where are the best WordPress theme designers?

Now that PressHarbor is getting off the ground, we’re getting a lot of inquiries about design shops or designers for WordPress themes – where are the good ones? Just received another email:

Can you suggest a very cost-effective, but a good design shop – an individual is preferred – to make some customizations to our site?

How about it – anyone know of a good designer/small shop that can create beautiful WordPress themes but won’t break the bank of the small businesses and individuals who need their services?

Please post your recommendations in the comments or trackback a blog post on the custom WordPress theme designers you recommend.
