Fair cost to replace 1 broken spoke in a tubeless wheel

So, I've got a broken spoke in my tubeless wheel.
I don't drive so can't easily get the wheel to a bike shop.

I've been able to find a mobile mechanic who will come out and repair it for me.

What is a fair cost?

The job will involve cassette and rotor removal, tyre and insert removal.
Make hole in tape and replace broken spoke. True wheel up.

Patch tubeless tape to make air tight again and re-install tyre, insert, cassette and rotor.

I get 1 spoke is really cost ineffective, but what would be a fair price to pay for the above job.

Many thanks

Matt
