AWS Migration and Setup Expert

- Why we are looking for help
The application currently runs on a single hosted server. It works reasonably well on normal days, but we have experienced slow responses during busy periods. Backups are handled manually, and when something goes wrong we usually find out from our staff or customers first.
We would like an experienced AWS freelancer to move the application to AWS and set up a secure, reliable environment that our team can manage after handover. We already have the application and a developer who can help with code related questions. We are hiring for cloud infrastructure setup and deployment, rather than a new application build.

- What we need from you
Review our application requirements and recommend a suitable AWS setup.
Deploy the application using VPC and EC2, with a private database and document storage.
Set up Lambda to process order confirmation emails in the background.
Configure security, monitoring, backups and a separate test environment.
Test the solution and give us clear deployment and recovery instructions.
