Real Outreach link building for Yoga and Gift niche amazon affiliate sites

hi,

I am looking for real outreach campaign to build links for my 2 affiliate sites in the yoga and gifts site. The links should be from sites with real organic traffic and preferably high authority in the niches mentioned. No generic sites will do.
Looking for guest post links and niche edits. Need at least 20 links for each site. pls quote ur best rate per link.
