Furniture layout Interior Designer Needed

I am looking for an interior designer to come up with the best layout for this space. I need it to include a dining table most likely 2200mm, dining chairs and an L shaped sofa, coffee table, side tables and three island chairs. The room needs two radiators and I need to find the best place for these. The sofa is to be in front of a fitted tv unit with shelving each side. I am also looking for an elevation of the wall with the television unit on and a good design for for a carpenter to make a tv unit with shelving either side. I would like all dimensions to be clear. Lastly I am looking for a lighting plan, three pendants over island, spotlights and one big light over the dining table.
