Lots of freedom you can choose your hours and vary your workload week to week. A decent pay per treatment, more than £50 an hour. The office are generally polite and helpful. You have an identity as a therapist, and can personalise your service. If you are a good therapist ans build a client base there is regular work.
Cons
It takes time to build a reviews and get the clients, can be slow at first. You are out in all weathers, travelling, and carrying heavy equipment. Peak hours are weekend and evening, it's not a day job.
