Personally speaking I think you might be pushing it asking for folks with maxed kingdoms. You're more likely to recruit a loyal member if you help them develop their kingdoms whilst being a part of your guild and reaping some rewards. I did this with my guild, gave folks time off donating or splitting it 50/50 say between kingdoms and guild tasks. They're more appreciative and therefore less likely to be trying to join a top 5/10 guild when they get higher ranked. Just a thought. Good luck, you should do well.
When I came here in September we were ranked 70 and I started gathering chilled out friendly types who liked to play often. We're 10th currently.
