Forge mod 1.16.5 -- 2

I am looking for someone who can make changes to my existing mod, it's 1.16.5 forge btw. The mod that I have is "Stone Age". Changes will be like adding new mobs with specific functions, making changes to existing mobs in my mod. I will also attach the mods to use later. But I will also send a video(if you are interested) so that you could understand how the mod already looks like. And yes, every single mob is already added to the game except HYENA. Here is the list of changes: A hyena mob(both male and female): -Like any single mob, they should walk around - Attacking mobs like auroch, boar, deer, terror bird, mammoths, player, mouflon, BUT only when in group of at least 4(for example, if there are hyenas nearby in radius of 5 blocks, they will hunt their victim) if this thing is hard to implement, do not do it, since I will spawn hyenas manually in my map -Hyena will see its target from 32 blocks(except for player, it will detect the player only from 12 blocks) -Hyena will decrease its speed when approaching a target by 3 times, and when hyena will be 5 blocks away from target, it will attack the target with full speed. When humans attack animals(the entities from my mod not vanilla ones ), hyenas will try to attack them too, and therefore, they will attack humans. Also, another change to add, when hyenas are low in hp, for example 5 hearts, they will run away. Differences between hyenas female and male: Hyenas female will have more health and damage than males. Also, increase the size of original hyena(for female) by 1.5 Deer: When he sees a hyena from 5 block radius, he will run away from it, but since it will have lower speed, it will die Humans: In the mod, you can see what type of mobs he attacks(from animal list), in addition to auroch, boar, mammoth he will also attack terror bird, deer, mouflon, fowl, and hyenas when in radius of 5-10 blocks( only applies to hyena).
