As they say in the classics 'don't give up your day job'.
And be warned, it's pretty typical for non-eu to get an L permit for the first two years, and that means that your spouse can't automatically work. It's not impossible (I did it after 12 months staying at home to look after the kids) but it takes specialist skills, the right qualifications, CV, perhaps some sort of process to have your university education declared 'equivalent' to something, and a fair bit of luck...
