I think it's easier to do in London, as the majority of clients don't live more than 5/10 mins walk away from a tube station or overground if within zones 1-3. Driving takes longer and you can't park anywhere without a permit. There are tubes every 3 mins and buses the same and you just swipe in/out with your oyster. No faffing about buying train tickets. I am mobile on foot (hello Spudclarke btw!) and currently do Spray Tanning and Shellac nails. However there is a big but and that's you are very limited on what you can offer. I'm trained in massage and I can't offer this without the couch as I would need a car. You are restricted in that way. I'm planning to offer Indian head massage instead, as that can be done on the clients dining room chair. I carry everything in a pink granny trolley, got the idea of a fellow SG! And carry my tent on my shoulder. I also know somebody who does it full time, has a full diary and just hops on and off the tubes and buses. I couldn't be mobile on foot if I was still living down in Sussex no way but in London it's more than possible as long as you can fit everything into a wheelie bag or suitcase
