Questions about venice beach california?

In venice beach how much do some of the streat performers make like in tenacious d (if uve ever seen the movie) KG is playing guitar on the boardwalk for money how much would some one like that make. And wat is the cheapest possible way to live there like I don't give a **** if its a shitty *** run down dump as long as its cheap and possible to sustain life in it. Cause after I graduate highschool I wanna hitch hike there and then play guitar on the street for money cause my favorite song is called going to california by led zeppelin. And in tenacious d that's where ronnie james dio told jb to go. Please don't make fun of my retarded idea of wat to do for a living just tell me if its possible to make a living there playing guitar and living in the cheapest possible place. Like I said please don't make fun of me I get enough of that. Just wasn't to spend my life doing wat I love playing guitar. Even if that means making a tiny amount of money.
