How much it take to take car rent 4 wheel?

I live in the UAE. I want to travel to Oman, Salalah, this August, inshallah. I want to visit some places where I can only take a 4-wheel SUV. But I don't have one. So I want to rent an SUV. How much will it cost if I rent an SUV per day? Please, can anyone give me proper information?
