To better fulfil your needs and budget, Dynamixyz pricing options are very flexible and numerous.
Just buy a permanent (lifetime) software license and optionally maintenance starting from the 2nd year. All our licenses are network based so you can use the software on any machine within the studio.
Use the system on a monthly basis, whatever your production volume.
If your project is short, Pay-As-You-Go may be the best option. Only the amount of final rendered facial animation is charged on a per-second basis.
