I think I have just the plane for you, I found it online while looking for some models myself. It is a free model as well.
Embraer Jets | FREE paper models
Scroll down the page and you'll find the planes Phenom 300 and Phenom 100. They have about 4 or 5 windows so it is definitely a small civilian passenger jet. Looks great as well. I personally like the Phenom 300 because there is more detail on the wings and tail of the airplane. Hopefully this site helps. Regards,
