You can pay in South African Rands. Please send an email to sales@awareim.com for details.
> ... do I first create the user in operation mode and then put a rule ...
No. Rules are entered in the Configuration Tool, which does not check existing operational data in any way. In fact, when you first create a configuration of your application, no operational data exists at all but you can enter all necessary rules.
> ... when I try to put the rule in I get a message saying their is no such user defined. or something similar.
Most probably this happens because you are not entering your rule correctly. I need to see the rule and the error message to be able to tell you more.
