Virtual Assistant for Backlinking

I need someone for about 4 to 5 hours per week to do backlinking. You need experience in finding linking opportunities with blogs, news, and others. The blog comments need to be well written. Social media expert with Linkedin, Facebook, and Instagram and others is a big help for the future. This can turn into many more hours and even full time in the near future for the right person. SEO skills are a plus.
