Whatever your "mad amount of money" is, there is no stages for your crankset. You got a used bike and at some point the original owner(s) replaced whatever was there with the praxis crank.
You have other PM options: hub based, pedal based, or crank based. There is too much you need to know, decide on, and explain for a single answer of buy this and this.
Spesh's OSBB and their ambiguous use of the term makes the situation more confusing. So, decide what PM you want and come back for more info.
Looks like 4iiii may have an option for your cranks.
