well my advice as a marketing expert you need:
-
improve the design of your website.
-
Ask for more reviews on Google.
-
you need social networks, you can show the before and after of your projects, do it as a reality for Instagram and Tikto, including a challenge of arriving at a destroyed kitchen and leaving it luxurious.
-
Have you done ads on Google?
-
Improve kitchen photos.
-
do promotions on Facebook.
If you need some help I can help you
for b2b, I would try linkedin, or google ads and other strategies, facebook is not so good for this
