Need a Developer for my server [Plugin]

Hi, I'm looking for a developer who could make a per-world motd and per-world login system plugin.

Per-World MOTD:
- clears chat per world.
- Welcome message per world (only player can see the message),
Ex. Welcome back Steve to Survival world!
- Worlds: hub, world, creative, skyworld, sg,

Per-World Login:
- When someone joins a world on a portal for the
FIRST TIME: Welcome Steve to Survival world! (all players can see this message)
2ND TIME: Steve joined Survival (all players can see this msg)

If you could do this and it works. I'll pay money
