Interior design for an Apartment

I'm looking for an expirienced home interior designer. In the scope of this task I need a flat layout and furniture arrangement. Some 2D/3D visualisation is desirable. If I'm happy with your view I have a lot of work for you including detailed rooms design, decoration materials and furniture selection. The appartment is for a family of 2 adults with a child of preschool/school age. We need to organize a living room combined with a kitchen. Which should have a dining zone and a rest zone with sofa and tv. Need to design parent's bed room. Child's bed room should have a game zone and a workplace for homework. It is also necessary to provide a workplace for adults, possibly inside a bedroom, but daylight illumination is preferable. You should provide enough wardrobes and storage. There should be a place for outerwear and shoes in the corridor. It is desirable that there are two bathrooms: the main with a toilet and a bath, and the second one with a toilet and a shower. You are free to construct walls and partitions inside. Restrictions: You can NOT move wet zones. You can NOT destroy load-bearing walls(bold in the picture). All numbers on the picture are in square meters, estimate linear dimensions proportionally.
