You can find a job in your specialty and the pay is very good. Prostitution really doesn't exist in SA. But as for women (locals), everything is very strict, they can't even drive themselves. But for immigrants everything is easier, as well as respect from men is tremendous, people are very nice.
My name is Rajesh and for one year I worked in Saudi Arabia in Butler's position. I had no problems at all with the documents, the country is beautiful and a good salary without any delay, I recommend it. I also give advice that you read all the papers you sign carefully!
