Amount of start up polishes?

[Tanning_Beauty]

Hi everyone, I’m employing a nail tech at the shop so have to buy products as my lady lady was self employed. New girl will be doing manicure and gels. No acrylics etc. What amount of polishes should I start with ? 15/20 ? Thank you

I personally would have more as if I was going for a manicure every week or gel polish every fortnight I’d prefer to have more choice.
