Getting Traction! Tips wanted

Hello there, I’ve done electrolysis in the past working for a clinic, and am re-entering the field. I’ve all the requisite materials to start, but since this is the first time I’m independently practising (in the city centre of a major UK city) I must admit I’m a novice with how to promote myself. Are there any tips and advice? A website, Instagram, flyers, &c I’m not sure how I should start going about this. Thanks
