I launched my airline miles award booking service, Book it with Miles, today! You can see it at https://bookitwithmiles.com.
Anyway, some of the technical details. It was built using Jekyll, a static site generator, and I used the theme bundled with Jekyll. It is hosted on Amazon AWS, specifically on S3 and CloudFront CDN for speed around the world (since it has an international audience). I chose zopim for a live chat and created a basic form-to-email script to email me the results of the contact form. After being contacted, I will work with the client on either a Campfire or HipChat chat room, then collect payment with PayPal.
