Buying an independent Iqama.

One of my friends paid around £15,000 for a Iqama  (princess Noor) at the end of 2014.

I want to know if there is a way to get this or any other iqama that isn't dependent on your employer as a sponsor.  I am currently in Saudi on a Multi entry visa that is valid for 6 months

Nope...Any visa has to be under a sponsor..
