AutoSell armor multiplier

Plugin category: Sell Multiplier

Minecraft version: 1.16.4

Suggested name: Amor Multiplier

What I want:
A plugin where you can get a set of custom armor for gems and that armor will give you a sell multiplier with Autosell plugin.
Also have commands to give and remove gems from a player (make these possible to do through console)
Also have a withdraw command that withdraws gems into a check in the players inventory, this can be just a emerald with the name "Gems" and a lore of how many gems inside. So if a player withdraws 10 gems, they will get a item called "Gems" and a lore like "Amount: 10" (next line) "right-click to redeem". Make sure that withdraw also removes from the players balance.
Make it so players can deposit the "Gems" item with just right clicking it.
Also have a placeholder with placeholderAPI like %amormultiplier_balance% , this returns how many gems the player have on their account (does not include the "gems" they have in inventory from withdraw).
When a player buys a part of a armor, they get the armor in their inventory, and the multiplier is applied when the player wears it.
