A small app on Google App Engine

Hi, I need someone to write a small CAPTCHA generator/checker in Python to be run on Google App Engine. All of the requests are to be sent by API requests. I already have implemented some algorithms for the image generation, so most of the work is to handle: * requests for new image * verification of user's answer It needs to be a somewhat secured implementation, e.g., just by using private/public keys. So the keys need to be retrieved from a datastore. You must have: * Created apps on GAE before and have proof (please send when you bid) * Experience with Python * Good English communication skills and a MSN account I've just started the site, so this is a small part of something larger. If all goes well, there may be other opportunities.
