Wanted: Ballet/other discipline classes for adult near Watford/NW London

[Blossom]

I have a friend who is in her mid 40s and has been dancing for a number of years. She has achieved Grade 4 imperial ballet, is about to take grade 3 modern and has also passed grade 2 tap (or possibly 3), all ISTD. 

 

Due to a combination of factors, her current teacher no longer has the hours needed to cover more than one discipline with her.  Any leads for schools or teachers who can run private classes between the Watford area and North West London?  She is very keen to continue graded classes.
