Android Advertising SDK

We need a banner ad SDK for android. We have developed a successful SDK for iPhone which needs to be mimicked for android. The SDK integrates with existing ad server. More details will follow through the bidding process. Looking for a SUPERB android developer (not someone who is just ok) who can work independently. This is a long term opportunity with more projects to follow if you are successful. We are NOT looking for development teams. Please DO NOT bid if you are part of a group or team. Individuals only. We want you to be part of our team. This is a very good opportunity for the right person.
