edocr.com (runs on Drupal) - Challenges of a tech startup

edocr.com was selected in 2008 as one of the 20 hottest tech startups of UK by Webmission08 supported by Doug Richard's of BBC's Dragons Den fame and UKTI. Soft-launched in Oct 2007, edocr.com will begin commercial operation on June 1st 2009. Not being a techie, I would like to discuss the challenges faced in developing such a product in a bootstrapped environment and the key role played by local community. Also keen to explore experience anyone has of running a Drupal front-end in EC2 AWS.
