I am an American communications consultant living in Tunisia. I have worked for numerous call centers here. You can see some of my experience on my LinkedIn Profile. I have worked with Stream, LaSorContact, MEA Global. This work is in addition to work I have done for other top corporations such as ATB, Orange, etc.
For me to do this job we will have to discuss exactly what you are looking for, to see if I am interested in doing the work for $800. Normally my hourly rate in Tunisia is between $50-$150 per hour, although if I am working from home, of course it can be less.
I invite for you to chat with me to discuss the project. If we can find a price we are both happy with I can guarantee performance, and would be happy to put you in contact with past clients, to speak to them on the phone, etc.
Hope to hear from you soon,
Joshua
