I need help to plan a Menu: 10 people, dinner with lovely friends at home
If I have to cook for a big group, 9 times out of 10, I go for scampi.
But if you use scampi as the second course, I'm not sure what to serve it with.
(I make it as an entree). Rice or bread, I'd say. I've never tried it with baked potatoes, but maybe it could work; or other options of course.

But I don't know if two times fish (in a broad meaning) works for you.

You can also make your meat in advance (stewing, ragout (of chicken, in vol-au-vent), meatballs) so you just need to warm it.

Edit: Oops, I just saw that this is an old question...
