Just a script I made a while back ago, for a reason I no longer can remember, its easy customized and should do the trick.
Easy Customize Options

- Token Cost (Activate/Deactivate)
- Token Amount Cost for each level up avalible
- Rank Protection (Activate/Deactivate)

* *Note **
* Token Cost disabled will return lead to free level ups *
* Also Rank Protection means that it prevents non-ranked players from using the gossiper *

!Notes are also within the script given about deactivating and activating!
