Which website to advertise for jobs in Skopje?

I am hoping you could help me,

I and a business partner are going to be in Skopje for a business trip. We are seeing a few people for a new job opening at our company.

We wanted to interview a few more people. Is there anywhere I can put a job advert out for free?

What is the most popular site in Skopje? How much is the cost of putting up a little advert? Or what is the equivalent to Gumtree here in the UK or Craigslist?

I look forward to hearing your responses. Email me at Protected content if it is easier for you.

Thanks in advance & best regards,
