Bathroom remodel layout designer needed — space planning from existing floor plans

I am remodeling a bathroom and have existing floor plans. I need help with layout and space planning for the project. The project will involve adding a window, maybe moving some non-structural interior walls, relocating fixtures if needed, and comparing different layout options. I would like ~3 practical bathroom/bedroom/closet layout concepts with pros/cons, rough construction implications, and clear drawings that I can discuss with my contractor. Ideal freelancer has experience with bathroom remodels, residential space planning, fixture clearances, shower/vanity/toilet layouts, and can work from existing floor plans. Deliverables are plan views and simple elevations if useful. I am not seeking permit drawings, 3D renderings, or help picking fixtures. At least not yet. Need a basic understanding of code requirements in the USA/California. There is no sense of urgency. Work to begin in spring of 2027. The attached image is the space in question. I will provide a video of the space and more details once a candidate is selected. Please reply with a brief introduction including why you think you are a good fit and details of similar projects you have done.
