White-Hat Backlinks for Manga Sites

I am looking for an SEO specialist to run a 2-month backlink campaign to strengthen the authority and Google rankings of two entertainment-focused websites.
The goal is to improve organic visibility, indexing speed, and traffic that converts into premium chapter readers.

What I need each month (Budget: $50–100/month):

• High-quality, white-hat backlinks only
– Guest posts on real websites (DR 40–60)
– Niche edits on established articles (DR 50–70)
– Contextual links inside relevant content
– No PBNs, no spam, no automated linking

• Pre-approval required
– Provide a list of domains before publishing
– Must be real sites with real traffic

• Final report each month
– Live URL
– DR/DA
– Organic traffic metrics
– Anchor text used
– Indexing status if available

Focus areas:
– Strengthen homepage authority
– Improve rankings for series pages
– Support premium/locked chapters through organic traffic gain
– Improve overall search visibility in Google North America

Project duration:
– 2 months only
– If results are good, we may continue afterward

I need someone reliable who can deliver clean, safe, sustainable backlinks that genuinely improve rankings—not quantity, only quality.
