To be frank...I think Flamenco is one of those styles you absolutley need to learn one-to-one...I've been taking private lessons from a Spaniard here in singapore for 4 months. He is very strict buty, it's really different experience to learning from videos....
Flamenco is such a technical style, I think it's important to have someoen who can correct you immediatly so you don't get bad habits...
