Backlinkanje po forumima

Looking for a SEO specialist for high quality white hat backlinks ( DA score 40+) in our niche.
Only relevant Croatian sites and forums  are considered.  
As a result we want to have normal backlinks (normal link on custom websites ) + keyword backlinks (some text + my keywords linked to my site).

Your job would be to write comments with a link in these forums/sites, topics are health-related. I would pay a fixed fee for every successful forum comment, which doesn't get deleted. I'd prefer someone who has previous experience with forum linking.

This is not a one time job. If you do a great job you will be hired again for
project that we will soon have. The budget can be discussable.
