I played for a while. And I can tell you starting your own guild is a HUGE time investment. You'll need the funding for a good hall and the money to fill that all with merchants if you want to have any kind of cred. If I remember correctly a hall is like 50k....I dunno it's been a while.
I just was lucky enough to start playing when my friend who was a leader of a huge guild decided to quit for WoW and gave me control of his old guild. Real nice imperial hall, fully stocked. I ran it for a while then got sick of the game and quit. IF you really want to start one I would say get to teh starting town and just spam the tade and recruitment channels
