hide admin sidebar menu options

I need to give a client access to the admin section to admin their users but do not want their admins to access anything in the 'CONFIGURE' section ... settings, plugins etc. How can I hide these items on the admin sidebar for any admin other than me (e.g. something like if(elggID=xxx){show items xxx}else{hide itemsxxx}? I have been able to unregister and/or hide menu items on the user pages but not in the admin section. Any help gratefully received.
