As far as "ranking up" is concerned, if you're looking for real leadership that might seem like it's of actual importance to the game and to the people you play with, it's going to take quite a bit of actual work before you can get anywhere, any "decent" (for lack of a better word) guild won't promote you at all without seeing what you do first in the guild, and asking people for promotions is more likely to get you kicked out than promoted. You basically have maybe 3 options:

1) Make your own guild, where you can be a master and control everything and promote/demote/kick people at will
2) Join a guild and actually put in the time/patience/effort(or money, depending on the guild, some may only require you pay them crowns either once or regularly) to get yourself up in ranks, which could take literally any time between a week to a year to be promoted to an officer.
3) Find something "new" where the rules are more lax and you actually can ask to be promoted, but I'm not so sure about those types of guilds.

Also, as far as "staff" is concerned, guilds don't have staff, nearly everyone in a guild is a "volunteer," because nobody joins these things expecting to get paid for it, and anyone who does probably isn't in a guild anymore, people in a guild are there willingly, not because they were hired.

Now, as for the other part of your "request," Retribution Council is currently recruiting, but ranking up will take some work as I just mentioned, if you want to try to join and see what happens, the guild page is right here, you'll have to post an application to join the guild, and once accepted(if accepted), you'll be free to go about whatever it is you're trying to do in the game right now, just maybe with a little more help on the side when you get stuck.
