Any of the big travel agencies would be able to issue an international drivers license for you. They will need your Qatar DL and your national ID, 2 passport photos and the fee (100 to 150 QR). It takes one hour if you try Regency Travel. Others might give it to you in a day or two. It is valid for one year and only outside of the issuing country(outside of Qatar) and only valid if used with your Qatar DL.
