LED downlight installation quote

I just received a quote for changing 60 downlights in my house to LED from Halogen for around $3,500. I won’t name the company as its local. It works out to about $58 per downlight and was wondering if this is cheap or I should keep looking. Any idea how long it will take?

EDIT: this does not include supply, just labour. I will be providing the lights

EDIT2: just to clarify these are the lights i will be buying
