We need developer to urgently migrate from Azure Servers

Project Description: Experienced developer needed to migrate a high complexity .NET App with database from Azure Servers.

Overview
The main application is made up of 3 .NET solutions:
Expertory1 (ExpertoryWeb and Expertory.FrontEnd web apps)
MainApp
Live

And two node.js apps:
encoder
Proxy

Several Azure services are used:
SQL Database
Redis Cache
Service Bus
Cosmos DB
Azure storage (blobs and queues)
SignalR Service
CDN

Some AWS services are used:
ElasticSearch
S3 (being phased out)
CloudFront (being phased out)

We want to move to Amazon Windows Server and not use Azure any more if it is possible. If it is too complicated we can move to another Azure account.
