Hmmmm. I just gave away Julian (literally, yesterday on reddit) in my other town, but I sure do miss him already. If you don't like any other offers for him I'll offer... 10 million for him.
But I would still like Marina when she's ready.
Edit* I'm also in no rush for Marina so if you need a few days to get her out, that's fine too! I wouldn't want you to lose any of your other villagers.
