Fossils and Archeology modification needed

Greetings

Im looking for a developer to modify a mod (Fossils and archeology)
Or make a plugin that can adjust settings in it.
If you are capable of modifying this mod so the rates of items dropping
Percentages of people getting items from performing actions.
These are the things i need to be able to adjust in the .cfg file.

The mod is Fossils and archeology revival 8.0.2 ver.
Im also running spongeforge-1.12.2-2825-7.1.6

You can find me on discord Oncyfia#8417

If you are able to do this, id love to hire you as a developer that could help with similar things to this.
