US inbound call center - answering

I'm looking for inbound call center based in usa with native americans only. The work will include answering the calls, following the script, following with the client and sending to them simple emails using our script. Im getting around 20-30 calls a day. Give me your best price for 1 week work. That's around 175 calls and average call is 6 minutes. So thats around 1000 minutes.
