Thing is Andy, money is tight for everyone else as well. I’ve seen other people in various lines of work trying to drum up business for whatever they do (understandably), but as everyone out there is worried and many on reduced or no income, I don’t think advertising for paid services looks great.
What I am already doing, is offering online help for mathematics, music theory and bass playing for FREE. This I feel is more in the spirit of us all “doing our bit” in these testing times. Should any of that morph into paid traditional tutoring at a suitable point in the future, then all well and good, but I am making it clear that it is offered with no obligation.
I’m not at risk of being homeless, cold or hungry, just a bit skint for a while. So I can afford to spend my time doing a bit of prep work and housekeeping to maximise the chances of the work flowing back in the future.
