My thoughts on what I have read so far...
Fee on guild creation: Well Depending on th situation this can be a good or bad thing, with how hard it is to make money in this game a very high tria price isn\'t viable.
Minimum amount of time spent in game: I have to be against this idea, I\'ve been in other games where some of the very good people only login twice a month or less.
Minimum Members: Due to time contraints it\'s probably difficult to get the minimum members all at once at the if guild creation, perhaps it can be a simple minimum like 3 people (different e-mails) And allow a guild to exist with less then that for about a week. In this method newbie guilds will die off gradually when the game checks that their time of not having enough members has passed. Though I suppose in this situation the counter has to be reset once they do get enough members.
Website needed: No comment... I think... the game has no way of telling whether or not your guild has a website.
Paying money to the government: I do not think that till will help RPing at all, more likely to encourage people to get money like mad. There might eventually or even already exist a guild which does charitable acts to help new players, such a guild will probably have very little loose funds to pay with.
A quest to get the permission to create a guild: I like this idea, but with the current state of NPC interaction some people might go insane before suceeding in making the quest. I do not know if the game support something similar, but instead of setting a flag or getting an item which gives you the right to make a guild, maybe a \'authorization\' code can be given to you by the game to give you permission to make the guild, of course this code would probably be a simple 4 character hash of your name(so it\'s character specific (saddly this means the guild founder must be the one to do the quest)), just to make sure people can\'t just infinitely loop the quest and then giving away the quest reward for making the guild. So I am made to wonder, what type of quest will it be? Tell Harquinst that you would like to make a guild and then travel to the city at the other end of ojaveda where the weapons merchant there will give you, your name specific code?
