Bathrooms Interior design and CGIs

Hi We are currently working on a renovation project in the UK and we need an interior designer with experience in bathroom designs. We would like to the designer to be familiar with UK shops and tiling companies and be able to fit in our own suppliers (we will provide brochures) within the design we are requesting initially a 2-option design with the aim to pick on design and work on the required refinement. Attached an initial sketch we would like to get a 3D image and adjust, an alternative view for this bathroom is appreciated. We have 3 more to be designed. The budget is initial.
