Love what you’re doing and the idea of a visiting barber. I would suggest keeping busy and active on social media and more so looking into a planning of attack for when we get given the all clear. Make sure your ready for when we’re able to get back up and running.
Also who’s your target market ? Anyone and everyone ? Males ? Females ? Kids ?
Why don’t contact some of the offices and businesses in the city offering your services. You could set up in the main lobby / reception area and staff members can book in a time slot which worked for them. Once this lockdown ends everyone will be rushing back to work with no time to get a fresh haircut and I’m guessing barbers / hair salons will start to get busy very quickly.
Also have you tried using a booking app ?
Booksy is a great app which connects to instagram / facebook.
