Need a call center (required for 30mins work only) in about 4 days time.

We need a large call center for less then 30mins of work only. We will need their staff to make calls simultaneously to one Australian number. Basically this is a competition and only first 10 callers will be selected for stage 1. The number will be revealed in about 4 days. I need your help to get in top 10. I will pay ($500 bonus x for number of times) I appear on top 10. Off course, more times registered on top 10 better the chances to get through stage 1 of competition. Let me know if you can help.
