Promote Unique Communication Product in Greece

I am looking for a skilled freelancer to promote a unique product designed to solve communication challenges in remote areas. The product has already proven its potential, especially in regions where traditional solutions have failed, such as Siemens' attempts. The target customers include municipalities and water corporations in Greece, particularly in villages or areas with limited communication infrastructure.

The freelancer should have experience in marketing and promotion, ideally with knowledge of the Greek market and connections to relevant sectors. The goal is to effectively introduce this product to potential customers and generate interest within three weeks.
