There's a lot of listings. I really like justlanded; its a lot better for listings more than 5000QR/month rental units. Another way is to drive to each tower and ask for the prices and if they have flats available.
The market is really small and an agent is really not necessary. Good luck.
For your price range, it maybe very difficult to find the Al Dafna area, especially the West Bay/Diplomatic Area.
