Feature Wall

I’m looking for a skilled and experienced professional to build a custom media wall in my living room, with work to begin in the third week of August. The required design reference is attached, and if you agree to build the feature wall at price quoted €4500 , you will take care of end to end build of the feature wall and arrange everything like timber framing, plaster, electrical work, LED lighting on each shelf and tv area, TV wall mount installation 55”, painting(Colour to be discussed), new Electric Fireplace 55”, all required materials, removal and disposal of structure/hearth. The professional should have prior experience building media walls (portfolio or photos appreciated), be able to provide a clear written breakdown of all work before starting, and offer post-build support in case of any issues encountered. The job must be completed to a high standard with clean finishing and proper safety compliance. I’m only looking for professionals who are reliable, punctual, highly customer centric, available within the requested timeframe, and able to handle the job end-to-end without hidden costs/terms to avoid surprises at later stage. I have taken measurements on the wall, measurements are approx and included in picture attached. I do acknowledge that the 1) wall length(top to bottom) on the left is not equal to right due to exhaust behind wall(top right side) 2) Boiler door at right side , so what can be done to maintain symmetry can be discussed before starting the work.
