MobArena Plugin Modification or New for $$

[Gorilla]

Hello all,

I am looking to create a modification of the MobArena plugin or a new plugin similar to MobArena. I imagine most people know of the plugin MobArena, if not, a google search will show you exactly what I am talking about.
MobArena is a highly configurable and interesting plugin to give players something to do when they're bored. It's like zombies for call of duty (Although zombies is definitely more fun than call of duty multiplayer).

Although highly configurable, the plugin, along with forks and other variations I've found, do not offer exactly what I am looking for.

I had a developer working on the project for a day, but his electricity has went out and has not been able to get it back up. I need this project done ASAP, so anyone who has time to get it done within the next day is much appreciated.

I have the source code of MobArena 1.8 as well as the source code for up to what the previous dev has worked on.

Additions/Modifications I would like:
-Mob HP and Damage Modification (Done or near Done by previous dev, some mobs don't fully work)
-Armor, sword, and bow durability do not decrease while in arena(Near done by previous dev, it works but visually some parts of this modification are odd and need to be fixed)
-Classes removed and players go in with their own items and carry them from the start to the end, any new items or levels on their items they get remain. Death keep inventory, xp, etc.(Done by previous dev)
-Death screen removed (Originally didn't even exist as far as I'm aware, but I think the source code version of MA has the death screen and spams warp commands until the player clicks respawn. Would like the player to just warp to the exit upon death as opposed to actually dying)
-When players exit the MobArena, their scoreboards are broken until they rejoin. I use SimpleScore and MobArena scoreboards for some reason completely kill SimpleScore's scoreboards from working after a game.
-An added PlaceholderAPI tracking the players highest round in a specific arena

Anyone interested please respond here or via discord Gorilla#5875

Budget is around $30, if you can't do that price please do not message me.

P.S. The server does not currently have a reliable dev, so anyone who is also looking for more work after this could get that if this plugin works out well (higher pay for future plugins knowing you will do a good job)

Thanks!
