Google Search Console professional to resolve Page Indexing Issues

I'm looking for an experienced professional to help resolve serious page indexing issues with my website. Specifically, I'm having trouble with www.myblacktree.com not being indexed - an issue that has been affecting more than 5000 pages. Additionally, I am receiving an unspecified error message in Google Search Console. I need a skilled professional who can quickly diagnose and resolve these issues. In addition to desired experience and portfolio examples, I will require references as to the quality of work that has been provided by the professional.
