I would go with a someone who offers full consultation and products that are not only aesthetically pleasing but also offers measurable results. Every room is different and should be treated acoustically as such. Take pictures and measurements of your room and start making calls to vendor’s on your list.
As far as being costly, think of it as long term investment. It’s one of those upgrades that outlasts any single component swap. Gear may come and go, but a well-treated room gives you a foundation to hear your system at its best, and the enjoyment just compounds over time.
