Hang on in there!!
I left college in 2009/10 and went straight into mobile work, it's taken time and even now there are days when I twiddle my thumbs.
I don't know how my earnings compare to other mobile therapists BUT I'm happy getting a full time wage and doing part-time (ish) hours.
I could kill myself doing back to back work, but I choose not to.
It does take time, Facebook I find is full of people looking for the next cheap deal, Groupon and the other voucher websites really have made the market much more difficult, but you need GOOD website and you need to work on getting on google. It's taken me a while but I come up on the first page of Google for a lot of my treatments - that's my shop front.
Now after saying all that, I am contemplating renting a room somewhere, mobile is hard work, I'm getting old and my back is feeling it too. It will be interesting just how my earnings go when this happens, if they go through the roof, I'll be gutted I didn't do this earlier!!
