Looking for a Chimney Sweep to do a Fireplace Insert Install

I can’t use any of the big name Chimney Sweep or Fireplace companies. I already have the fireplace insert and all the big names want to sell that to you. I understand that. But I did some work for fireplace wholesaler and have a brand new insert already. The big names have given me quotes between $6k-12k for what one of them told me was “one days work for a couple guys.”

I need someone willing to simply install it along with the pipe to the top of my chimney. Anyone got someone that can do this work? I would really appreciate it.
