Backlink Building for Environmental / Recycling Business Website

I’m looking for an experienced SEO backlink outreach specialist to help build real, high-quality backlinks for an electronics recycling / environmental services company based in southern California. We already have local citations/directories, so I am not looking for citation building. I’m looking for someone who can find and secure backlinks from real, relevant websites in the environmental, recycling, sustainability, waste management, local business, education, nonprofit, property management, and community space. Good backlink opportunities may include environmental blogs, recycling resource pages, sustainability websites, San Diego business/community websites, schools, nonprofits, property managers, apartment/HOA resource pages, chamber/business association pages, local news/blogs, and partner/vendor resource pages. I am not interested in PBNs, spam directories, blog comments, forum links, profile links, Web 2.0 links, automated link building, cheap guest post farms, or fake “high DA” backlink packages. Quality is much more important than quantity. I would like to see examples of real backlinks you have helped secure, especially in the environmental, recycling, sustainability, or local business space. It would also be helpful if you can provide a sample list of potential environmental or recycling-related backlink opportunities before starting.
