Finding a manufacture

We need a Serbian native-speaker, who would help us call Serbian manufactures, using numbers we already have. You should ask 5 questions we have (For example: Are they looking for parthners, can we get their number, so we can reach them out), write down the answers they give and then give all of the information to us.
And also help us find another manufactures in Serbia, which would produce clothes for our clothing brand.

We are also looking for a Romanian and Bulgarian native-speakers, who would do the same task, but in Bulgaria and Romania. Same task same payment.
