If you hit the "get it now" button at the top of the page Dan sent, there is a "Live Sales Chat". If that is working, I would start there if you have more questions.
The buy or trial link takes you https://marketplace.arcgis.com/listing.html?id=3855a9d026f64917a09bfc78b590c42f But you will need a developer or enterprise log in to go to the next step (e.g., to see the cost).
...also, remember to check Dan's response as correct if that answered your question.
edit...once you sign on you get this note (no pricing yet)
