Each developer will have a different minimum quote for the project. It really depends on how complicated the integration will be and often the minimum is quite high just in case the project is very complex. Don't be discouraged by the prices listed in the expert board.
If there is lots of sample code available already from Articulate then it might help save a lot of time. It may require lots of custom coding to get it all working though. I would reach out to a few developers and see if they can give an estimate for their services.
