I am not the right fit for every WordPress development project. When I have to turn down a prospective client project, I recommend another developer when possible.
Often I cannot think (or do not know) of a specific developer that meets the needs of the project. I want to be helpful, so I do the next best thing. I suggest three resources that list quality WordPress developers:
WP Candy Pros
WP Candy, the WordPress news and information blog, hosts the most complete directory of WordPress professionals. The directory can be filtered by region, specialty and price range.
WP Engine’s Consultants
The specialized WordPress hosting service, WP Engine recently started their own consultants/developers list that includes specialties, bios, price-ranges and contact information. The consultants/developers WP Engine lists are hand-picked as resources to recommend to their own hosting clients.
Code Poet Directory
Automattic, the company behind WordPress, maintains the Code Poet Directory. The companies and individuals in the directory can be filtered by region, specialty, platform and price-ranges. Those listed are considered to be enterprise-level WordPress professionals, web designers and developers.
