Hi maddi,
My guild, Lolcats, is pretty active and has a few openings. We used to be $30k/week but we’re in the process of upping our weekly requirements. This week is $60k and after that it’ll be $100k/week. Despite being higher than the $30k you’re looking for, I think you’ll find being a member of our guild will outweigh the extra gold you have to contribute. And you should still be able to get your kingdoms leveled reasonably fast.
If you’re interested (now or in the future), just lemme know your invite code.
