I'l add following regarding CZ residence:
Except company you can also get trade license which is cheaper,you can also get a job,and last what is also funny-get visa if you get GF there.I dont know does any other country in world gives visa simply based on relationship,in most cases you need to be married.There are other type misc visa types like student visa,bank account visa,research visa,etc.But those 3 which i mentioned are most common.You can also visit this url to get more info about registration process:

In shortly no country beats CZ when it comes to easiness of immigration.I think all porn people should move there ;)
