Denied [All Main Servers Suggestion] /sell command (Rankup bonus)

In Game Name:

What part of EcoCityCraft is this suggestion for:

All Main Servers​

Short title for your suggestion:

/sell command (Rankup bonus)​

What are you suggesting:

When you rank up, from builder to resident to mayor etc... Or when you donate, and getting $, $$ etc... You should get more and more good prices for stuffs you sell. Lets say if a player wants a shop, and he is a President, his /sell hand prices is maybe 10% higher than Mayor, so more players could have shops, increasing the overall competition in the shop market.

My example of this:

Builder: +0%
Resident: +10%
Mayor: +20%
And so on, 10% for each rank, max 60% for EcoLegend

And for donators:

$: +10% additional to the ranking percentage
$$: +20% additional to the ranking percentage
$$$: +30% additional to the ranking percentage
And so on, 10% extra for each donator rank.

This would make it more fun for the long term players, and more fun for the new players, they get a challenge, and they know they will get cool benefits when they rankup, which i will guess will make them stay longer, and overall increasing the playerbase.​

Why is this a good addition for EcoCityCraft?:

This is a server for economy, making perks for higher leveled users, and donators would increase the joy of the server, aswell as maybe gain some more donators if you apply the ability to donators also, as i would recommend.​

Other information:

I've written it all in the "What are you suggestion" spot.​

Plugin or custom addition:

Custom addition, i couldn't really find a plugin that does this, so i think this is something you would need to add custom.​
