If you look for one type of service you need to wade through many unrelated threads. There is no way to find the highest rated service provider.
It would work well to move this to the resource manager, because that would allow categories for each type of service, reviews, portfolio and it will also allow customers to see which addons/designs the service provider has released in the RM. Customers can also see the top service providers.
Besides the advantages as a much better index of service providers, it also showcases the usefulness of the resource manager as a product.
