I am looking for recommendations for medium - large agencies that are IA ninjas. Currently in infancy, I have been tasked to research some medium to large agencies who are known for their IA skills.
The ultimate goal is to put together a budget to create the following deliverables:
1. a sitemap of the current site (which is an ecommerce/lead-gen site) that is about 15,000 pages
2, a new sitemap of the future of our site
3. Wireframes and annotations for templated content
