Bathroom refurb design with 2D plan and 3D images

We are doing a bathroom refurb in a London Victorian house. We would like to have a redesign with 2D and 3D images.

This is a folder with images of what the bathroom looks like now: https://www.dropbox.com/scl/fo/m1js3obsn52fkzy81krzg/AGrFW39vhaPIutSD-T7BuUw?rlkey=my3rzh9aruxlspmroui59l1d3&dl=0

And I've attached an image (cut and pasted bits of lots of pictures) to create an idea of what I'd like the bathroom to look like. There are built-in alcoves / shelving with lighting. I took the pictures from these inspirational images: https://www.dropbox.com/scl/fo/tph5inh58kiy7sv94cw2c/AGNqt_V2NAkxxfxOF7_59IA?rlkey=axqdpy4c8355boqqtsof8t882&dl=0

I've also attached an estate agent floor plan of our house. You will see the bathroom dimensions on here. The height is 2.7m.

We want to put a shower (wet room style) where the cupboard is.

I can also send you links to tiles / taps / baths / basins / toilets I like so that you can include something similar in the design.

If you are interested, please give details of:

1. Will there be a 2D plan and elevations with sections?
2. How many 3D images?
3. Will you recommend any design alternatives?
4. How many revisions?
5. Will you include a source file? In which formats?
6. What will the time scale be?
7. Can you also produce Construction / technical drawings for the builders? If so, how much extra would this be?
