Sera Yapi Bulgaria Import and Export Companies

I am looking for a company that manufactures greenhouses. The manufactured greenhouses will be sold in Bulgaria and used in people's home gardens.

I am interested in having a greenhouse built (house-type or another shape) with dimensions of 2.60 x 3.60 m, a structure made of metal/aluminum profiles, and covered with 6 mm polycarbonate. Additionally, I would like two windows with automatic temperature-controlled opening. Do you manufacture according to custom sizes?
