i agree with most of the people about how id be skeptical to take your class.. please dont take this the wrong way.. but from the perspective of a person that doesnt know you, or your back ground, id be very sketchy... the questions that would run through my mind are "is this a scam?"... "shes not licensed or anything.. how do i really know that shell really help me improve"... etc etc... and like, if i had a choice to take a class from a licensed instructor and a non licensed one, id go with the licensed one just because they sound "professional"... its nothing against you or anything at all.. its just that people like to see the degree or license before they are willing to shell out money..
but id say go for it.. dont make it a full on business though.. i wouldnt exactly open up a full store and such if i were you.. id probably do some small test lessons first.. like post up flyers and such.. and hold a few small lessons at your house, or a community center, or something like that for a bit cheaper than youd normally charge.. see if you can actually handle the teaching.. and see if the students like your class.. if everythingworks out well, than id say hell yea, make it a business down the road... but for now, start out small.. take baby steps.. test out the waters... and then make up your mind
thats my take at least.. good luck!
