Shower enclosure glass door with glass panel on wall

Hello,
in our guest bathroom we still need the shower enclosure. I have uploaded a photo of the shower.
We have deliberately chosen a half-height wall to make the bathroom appear more open through a glass pane on it.
The shower is 1x1m.

Now my installer has had a technician from the company Palme take measurements. The quote is now around 2000 euros.
Not exactly the price we had in mind.
Do you have any tips on where to get a good and cheaper glass panel with a matching door?

Obtain various offers from glaziers in the area. We have a glass wall, there were offers ranging from 800 to 1800 euros.

We also had our (Ganzglas) showers made by the local glazier, as well as some wall coverings behind the toilet and washbasin. I would estimate that such a pane including installation should not cost more than around 500-700€, depending on the remaining height up to the ceiling?

Thanks for the tip about the glazier. I'll call some on Monday. I wouldn't have thought of that.
