I want to start dancing?

Ok, so I'm 13 and I wanna start dancing (hip-hop) but I want to lose weight too(I weigh 163). I wanna be good like the crews on America's Best Dance Crew (mostly I.aM.mE). Any tips? I can't take dance classes so do you have any good youtube videos? I wanna learn tutting, popping, breakdancing, and shuffling.
