Job: Addon that let's play custom sound files when a player enters a area

I need an custom addon that lets me do the follwing:

1. Set in-game areas
2. Play custom .ogg files in said areas (in-game music)
3. Settings that prevent certain jobs from entering certain areas
4. Naming areas
5. VIP only areas

The price is negotiable and I am not too fussy about when the job is complete, so long as it is done within a reasonable time. The most important parts for this addon is the VIP only areas and the custom .ogg files being played in certain areas.
