Please can someone help me with where I should go to register as a sole business if I live in Ferney-Voltaire but have clients also in Switzerland??  I´m a private yoga therapist, so my ´business´is just me, address is the apartment my boyfriend rents.... I´ve been told to go to the Marie where I live or a place in Bellegarde but not what papers I need to take etc!!  Don´t speak French so not getting info I need easily!  THANK you in advance!
