help again???

I am in the midst of research so I can pitch an acting class idea! Just wondering where I can find some info on insurance/legalities? Website4s??? Information, greatly appreciated??? Also, I have an understanding that formal training is needed to teach an acting class... is anyone aware if there are any specific training fields required and if so, what they are??? Thankl again guys. Oh and I didn't get many reponses to monologues??? What are some favourite female 1-2 min monologues from contemporary plays (great plays)???
