Starting a business in Riyadh

I am planning to start a business in riyadh. this business will be mainly about supply any thing to any company they need.

Looking for your advices about it.

The only thing I know is you need to have a Saudi as a business partner. 
Just visit Chamber of Commerce and maybe you will get some good advice there.

Depends on how you want to do your business, as an investor or as individual. If individual as kailash said you need a sponsor and this might not work well with the new regulations in place and there is always a risk of sponsor "repocessing" your business.

If an investor then you better visit sagia website to know more about this.
