3 niche guest posts (10 USD each)

I need 3 niche guest posts (on 3 different websites) to be published, each guest post should have a do-follow backlink linking to my website. Guest posts should be on DA50+ websites with 1K+ traffic. PBN wont be accepted, articles with illogical text, writting errors or spinned articles wont be accepted. If done well more orders will follow.
