Advertising private tutoring


I am interested in doing some private tutoring as an alternative to teaching in the classroom. Can anyone help in regards to what I need to do to set this up? Do I need insurance of any kind? or anything else alongside my crb check?

Where is the best place to advertise? I have looked on some websites but don’t want to get into the whole having to pay commision to companies so any tips of where to advertise and how would be brilliant? I also checked few sites Tutoring Services Video that would help but did not found much.Please help me out.

Any help will be appreciated.
Thank you in advance
