Need support for AWS & Cloudflare connection.

I am looking for experienced support to help me connect my AWS services to Cloudflare. Specifically, I need to connect EC2, and may need to setup some DNS records. I also require support to figure out what additional services I may need, as I recently encountered an Error 522 Host Error. I have expertise in CloudFront, EC2, and S3, but I need the help of an expert to complete the connection between AWS and Cloudflare.
