Windows Replacement in Riehen

---

I apologize but since my German is not good enough I hope English will be fine as business language.
I bought a house in Riehen and I need the following works:
In the Ground floor:
A) 2 windows (~127 cm x 120 cm) must be dismounted and replaced with 3 windows shorter (~110 cm high) it will require approx 10-15 cm brick to install them. There will be 3 windows instead of 2 since one of them will be split in two (a new wall for a new bathroom in the middle).
Note, I already have the new 3 windows, I need the dismounting and installation handwork.

B) I would like to replace the existing shades (3 windows ~125 cm wide) with new shades and electrical control.
For shades I need the full package, material and installation.

In the basement:
C) One window (old single glass) to be replaced with a new one (I already have the new window)
D) Two old windows (singleg lass) to be replaced with the two windows dismounted from the ground floor (size are very similar)

Would you be able to provide an offer and complete the job in the next 2 weeks?

I can speak Italian and English, just basic German.
Thanks in advance
