We used Infect for a pretty big job on a new lander. We didn't give him anything to really work with, and it was a niche that didn't have much in the way of landing pages to get inspiration from.
Somehow, Infectisites made a lander and order page that was fuking amazing. He went above and beyond all expectations, and created something we couldn't have thought of ourselves. This guy is the real deal. His turn around time was fast as hell too. We definitely recommend using his services, but we'd rather you didn't use him, so we can get him working for us all the time.
If you want a kick ass lander, use Infect.
