Well, I coached and taught in chain schools, all over the States for over 30 yrs ( thru 2005 ) and depending on location, there is ample opportunity for female teachers in the larger metro areas ( especially trained ones in either Amer. or Intern style )
Even in some of the smaller towns I visited, there was ALWAYS a full time lady teacher ( and I dont mean the owner ).
As to income, there are many who now give guarantees .
And..at $15 per hr, that is WAY above minimum wage plus benefits like dance training and trips .
