Stone kinds importing Bulgaria

Hello, I am L**** L***** from Varna, Bulgaria and I import natural stones for the needs of the construction business. I have a small showroom where my customers can touch live some of my materials.
I advise both large construction companies and private clients in interior and exterior solutions for the home. I am looking for partners to work with.
I am interested in granite, marble, limestone, basalt,
I am also very interested in the increasingly popular decorative wall panels in Bulgaria.
