Review and restructure Cloud Architecture within Google Cloud

We are using Google Cloud Platform (GCP). Happy to accommodate a team trained on AWS/Azure if your team is happy to step up and learn GCP. Is this within your scope? We are using GCP badly in many ways. Examples: No VPC, many problematic development processes, poor DB update process (MySQL), security holes, poor API design. Our problems span infrastructure, development and product design. Goal: with a primary focus on cloud infrastructure, review and then reorganize our development system toward today's best practices.
