Great, You are looking for some worth information anonymously!!!

Please don't give this worthy information without knowing his identity and purpose.

I am also willing to share my experiences only if he / she provides some information about him/her self.

If you want to give some statistics about some thing to some one, you need to have a lot of transparent data about it. The problem is that IT in Iran is small and is not transparent.
So my friend no one can give you such worthy info :)
No one will also blame himself for low quality.
