Hello there!
I am 34 years old, with more than 10 years of real professional experience in network and server administration, I have worked with Nestle, Ozone, LAN10, Project tur & taxis and many other small enterprises..
So this is a quick and easy task, just configure the allow-transfer and notify on the primary server then declare the zones on the secondary servers..
I can do it right now, I am free until tomorrow 3 am UTC, otherwise I will be free on monday, almost the entire day, you can contact me here on freelancer or on skype: protojob, I am also available on viber, whatsapp and google talk (hangouts)
Hope you get this issue fixed quickly, I wish you the best, regards.
