I think another viable route is hiring a contractor to build out your environment for you. We got a quote from an AWS contractor and it was reasonable for our setup, but ultimately we really wanted a PaaS. Unless you’re an expert in HIPAA and the cloud platform you’re looking at, it’s not something I would recommend tackling on your own.
Remember that there are a lot of non-tech parts of compliance to consider as well such as training, physical security, security assessments, etc.
