Device Enrollment program

I would like to know who can support me with enrolling iPad devices to DEP in Saudi Arabia, when I contacted KSA support they had no idea about DEP and asked me to contact developer team in US. My organization already has ID for DEP, I want to know who can support me with enrolling devices I buy into the program. Last week, I had to configure 20 devices manually and we are

buying more devices coming weeks and I need this support , because the manual configuration takes a lot of time and efforts to finish the configuration. Please help on this topic.
