Please don't bu**s*** and mislead people. In the public service, grade is what determines your salary. 9k - 12k is a DD - D level, meaning at least MX10. That requires you to have minimum 10 to 15 years exp in a similar role.

If you are going in as Manager, it will probably be MX12 (1 - 4 years exp). Depending on your last drawn salary, the max you could probably ask for is $4,500 thereabouts.
