This will be the level of Twitter and Facebook. I am looking for help with the establishment, management and operation of the company. People that specialize in contributing to the great success story of the company.
I would suggest checking out cofounderslab.com. They have a great service with a free tier that allows to to mingle with other people interested in starting like minded businesses. Through CoFoundersLab you can actively look for people in specific regions or people with specific skills.
You have to understand, Saudi Arabia is the most conservative country in the Middle East, and anything that may allow men and women to contact one another is strictly prohibited. The fact that you want to introduce a "social networking" site will not be looked upon favorably. Yes, they do have Facebook and Twitter, but it is quite common for them to be blocked or shut down.
Other than the cultural aspect, Saudi Arabia is like many other countries in the region: the best way to establish a business is to build relationships with people who may be able to help, or know of people who can help.
Since an invitation is needed to enter the Kingdom, making contacts while you are here is the only way you will be able to get inside.
I suggest you go on LinkedIn, and other business sites frequented by people in the Middle East and inquire if anyone is interested in filling the roles you need, or know someone who is.
Lastly, you will need to be patient and persistent because nothing is done quickly there.
