Chat for Podio

We need to have some kind of chat integrated with Podio. [login to view URL] Podio has an open API and the documentation will be online soon - there is a Podio API space where all information is ready. What we want is a bid on how much time this will take and how much money. Podio is an online work platform divided into organisations and apps - we want to enable the users to be able to chat and when they are finished with the chat to save the chat with the app they started the chat from. The chat could be like the facebook chat or it could be an integrated chat with like skype or similar.
