Hiya,
Welcome to the world of Mobile Beauty Therapist, I am a mobile therapist and thoroughly enjoy my job, my advice would be to make sure that you only take bookings by phone as I have had MEN trying to book by text...... You need to be very careful if offering your treatments to men as you will be on your own. By all means do men you know you are safe with but not on your own.
Good Luck.
p.s Yes make sure your couch isn't too heavy although you will get used to it!
