I've been a full time private tutor for almost five years, tutoring mostly A level but with a handful of GCSEs as well. I started with an agency (for about six months) and I now work completely as an independent. At A level, parents want 1 to 1 tuition, and I have plenty of work. I don't advertise at all now, although I did for the first couple of years. I have a primitive website that I wrote myself, that does well in search engines in that I am the first independent tutor in my subject in town behind about eight agencies. Parents who contact me do so because they don't want to use a tuition centre, an agency or a national website. My clients mostly come word of mouth these days but I am still phoned by some who have found me on the internet. I am now really busy, but it didn't happen overnight. The work slowly increased over about three years before I reached what appears to be my natural capacity.
