The hashcrypt team was one of over 200 applicants that we trawled through and it was a good decision. We purposely did not give them very much of a design brief to see what they came up with - we only provided logos, images, text, and page titles and he came up with a couple of nice WP sites for us. They work very fast and follow instructions well. Their team also communicates well and prompts with patience, as it was often they waiting for our feedback to progress.
