Hi,

I am also in the process of setting up my own business here, although in a different field, I am offering communication coaching.

However, I have made some inquiries and it seems that there is no specified amount that you have to pay the sponsor. Any Qatari can sponsor you and it is up to them what they charge you. I have heard that a lot of them go for a percentage of your revenue rather than a fixed amount...

Sorry, I don't know the answers to your other questions yet. Would like to know myself...
