Putting some rooms in the NPC

[zmref]

Help I'm a newbie I don't know how to do this, I'm requesting for a code that when I clicked the NPC:

1.) 10 rooms will appear and when I select one of the rooms...

Example:

Room 1

Room 2

Room 3

Room 4

and so on..

2.) NPC will ask to create a room with a price that lasts for 30 mins and when time's up the player,party or guild will be warp out. then the room is available again.

Example:

-Create a room for guild //Room Cost 100,000,000

-Create a room for party //Room Cost 50,000,000

-Create a room for self //Room Cost 10,000,000

3.) The name of the player or party or guild will be putted on the selected rooms, also the room will

count the player/s in it.

Example:

- PlayerName in Room 1 (1/50)

- PartyName in Room 2 (12/50)

- GuildName in Room 3 (20/50)

4.) If the room is taken the new player or new party or new guild can't create a room thus making them to choose for another room available (10 rooms).

I want I want I want please and this might help for others that seeks for room creation.

Thanks in advance
