Looking for ballpark pricing on AX.

Hi, our company is in early stages of investigating Dynamics AX and I am needing someballpark Licensing Costs for strategic budgetary purposes. Can anybody please give me some approximate price ranges based on following assumptions?: Premier Service with Enterprise Agreement, full capability for Discrete Mfg and associated Finance, a 15 License pilot implementation growing to 700 License over 3 years. Any input on ballpark range per Named User would be very helpful (I understand User categories are Enterprise/Functional/Task). Thanks.
