Javascript based xmpp client - open to bidding

I need to implement xmpp chat, probably using strophe library. I will also need some other work done for the project that I making later, so if we enjoy working together you can join our team. I am writing most parts of the project and hence just don't have enough time for this bit. The chat will be 1to1, so no chat rooms, unless a user creates one. The xmpp server used will be chosen later, and can be anything. The chat client needs to support prebinding (authentication of user with chat when he logs in to website)
