Starting salary for inexperienced dispatcher in UAE is typically 10,000AED/month. There are of course people out there who take less and then screw themselves and everyone else.
You'll most likely end up working somewhere second/third rate for a while like midex/aerovista/dolphin/rak airways/Eastern Sky/global jet.
The pay and conditions in these places are not good but you'll get a start at least.
The VIP operators are worth a look too.
It is not easy to get a first position and contacts are everything.
If those people at the Jepps school told you that you could apply to the biggies like Emirates/Etihad/AirArabia and FlyDubai then they should not have told you that as these airlines typically don't take new grads.
Keep your eyes on the job sites.
I believe globaljetdubai is looking for new dispatchers.
Good luck.
