Developer Needed for Humble Bundle type site

Developer Needed for Humble Bundle type site- Pubnub realtime Stats, checkout option and download counter

I need a developer that is capable of putting together the above on a wordpress site.

The site is located at http://demo1.twentyeleven.co.uk. What needs doing are 3 things, firstly the counter that I have implemented on the front page needs to be linked realtime to any sales that are made.

Secondly a chekout option is needed with Google Checkout, Paypal and Possibly amazon, i'm assuming a plugin could be used for this. The checkout option must include unique download keys supplied by email to the buyer. I've looked at a few existing plugins and there are some that can deal with this.

Most importantly is the metrics and tracking that follows a purchase. Examples of this can be seen at humble bundle, indie gala and indie royal. All rely on pubnub to display realtime stats. We need to display the same stats and graphs that are used on these sites.

Sign off for this site is mid June so I need someone quickly for this project.

Please feel free to ask any questions.

Many thanks

Nigel
