Message me your Skype info. I'm partnered with a sales call center in Guatemala CIty, Guatemala. We do not do any customer service or tech support campaigns (although we have partnerships for those), we specialize in and focus on sales. I personally spend 3 weeks out of the month down here developing the staff, optimizing the campaigns and managing the client relationships. 75% of our agents grew up in the US and were deported as teenagers or young adults so their English is top notch.
Send me your contact info when your ready to discuss the options available.
