Krissovo,
I am in the magic community and there are many magicians who make a living busking. You could always look over their threads in
www.themagiccafe.com. If you need any more help, I could send you some pdf's of busking texts for street performers.
Never taken the guitar on the streets, though. But remember, the louder it is, the more people it will attract. And you've got to decide if you want to be a player or an attraction. You could just stand and play, or have the audience help and sing along and request songs, etc.
Best luck.
