Vanilla notification plugin

We're trying to find a good PHP developer to write a small Vanilla forum extension for us. The brief in brief is this; we need to hook parts of vanilla 'New post', 'new reply', 'new user' (possibly a few others - an idea of what could be easily hooked would be good) and make it pass a notification with details of each to a product we are working on (e.g. title of post, name of person registering). We have a simple API in PHP to get the data across to us and the learning curve for it is pretty shallow. If anyone would be interested please post a bid and just give me a brief idea of your background and how you've worked with vanilla in the past. I can fill the right developer in with more details and documentation on our side of things but it is sufficiently documented and easy to work with.
