Not to be rude, but hiring for config editors? Seriously? Doesn't a developer in a normal MC server do that, can't you just search up a tutorial for the plugins you want its config(s) edited? Also I can give suggestions for plugins, but IDK what t give since you didn't really give a description of your server.
If you're planning to have minigames, I would recommend BungeeCord (not really a plugin but still good), Multiverse (obviously and along with Multiverse Portals), along with separate plugins for each minigame (for UHC I can specifically recommend UHCCore), and if the server is cracked, I can suggest AuthMe Reloaded and SkinsRestorer. If you're also planning to have Skyblock, then I'd recommend BSkyBlock (basically ASkyBlock but for 1.13/1.14). If you could make a specific description on what is gonna be on the server, then maybe I can suggest plugins you'd actually use.
(Also here's some more basic plugins you probably should already have:)
EssentialsX
PermissionsEx/GroupManager++
WorldEdit
Vault
WorldGuard (if you want a unbreakable spawn)
EZColors (useful for chat colors if you're planning to have ranks)
etc.
Anyways, hope your server does good, and bye!
