I've never been one to focus on HNMs, but I believe that finding an HNM shell (meaning one that actively camps the Land Kings) will be harder these days. I can't really think of any atm, however I think it's due to the fact that most linkshells have now become specialized. By this I mean they schedule certain events on their calender and if a King happens to be up, or a window is opening soon, then they will give it a shot.
I assume since you are looking for an HNM shell, your ultimate goal is to obtain some of that awesome gear. I'm not sure if you will find one that will be able to work with you and your schedule since you already have other commitments. What if a window is open when you are supposed to run with your Sky LS? Luckily, some of the HNM gear can now be obtained from Einherjar (minus some job breaking items, e.g. - Ridill). Depending on what your ultimate goal is, you may have better luck looking for a group that does Einherjar or ZNMs instead.
I've always just searched or camped at the associated areas when I wanted to know who was up to what. You could probably post on the other forums (KI and maybe BG) and use the advanced search feature on the FF Community site to help find something: http://fanzone.playonline.com/lscom/index.do
With all that said, the few out there probably have a pretty good monopoly on some of the HNMs right now >.>. Send me a PM when you find one lol..
Good Luck.
