You can give a try by calling USCIS and asking them to expedite. They ask for one of the several reasons required to expedite your processing. You should clarify that if you won't get EAD on time, you will lose the job and it will be sever financial damage to you. 

I was in same problem last time, I got OPT in 3 weeks after I called them. I am not sure I got it faster because of the expedite or not. But I suggest you to call them and request. That is the only thing you can do, rest is to wait. Good Luck!
