Mouse control software (custom profiles and loading into NV memory of the mouse)

Looking to create a software to re-program any of my mouse buttons. There are 24 buttons plus a scroll wheel plus some other unique features on this mouse.

We are trying to provide the ability to create several custom profiles for this mouse and save these profiles to the mouse and the computer for later editing. This software should be quite similar to other mouse programming software out there in existence and therefore it would be helpful to have some familiarity with these types of software.

This software must work or have version that can easily work with Window, Linux, and Mac.

Let me know if you have any experience in this field please.
Any level of experience using this kind of software.
What kind of approach you’d take.
Roughly how much this would cost (very rough and we can refine and figure out the details).
