Need High-Quality guest post & backlink opportunities (USA SEO)

I run an SEO agency focused on affordable SEO services for small businesses in the US.

I’m looking for someone experienced in link building and outreach to help secure high-quality guest posts and backlinks.

Our website (for context):
https://www.zoi-digital.com/

What I’m looking for:
Guest post placements on real websites with traffic (not PBNs)
Niche relevance: SEO, marketing, SaaS, small business, ecommerce
Sites with US traffic preferred
Do-follow links only
Ability to suggest and/or handle outreach

Requirements:
Share sample sites before starting
Provide metrics (traffic, DR, niche)
No spammy link farms, no AI-generated garbage sites
Bonus if you:
Already have a network of websites
Can offer bulk deals or long-term collaboration

Goal:

Build a strong backlink profile for a new SEO agency targeting US clients.

Open to per-link pricing depending on quality
