Comprehensive Web App Hosting Assistance

I'm looking for a professional to host my web application. I need someone to run iit for me on their test environment to show client it works, once they are happy we would need advise on hosting and to set it up in production environment. As for the hosting environment, I have no specific preference, so any will do.

Key Responsibilities:
- Choose an appropriate hosting environment (shared, VPS, or dedicated)
- Set up a test environment for my web app
- Provide comprehensive assistance throughout the process

Ideal Skills and Experience:
- Extensive knowledge in web hosting
- Proficiency in setting up test environments
- Experience with various hosting environments and operating systems
- Excellent communication skills to ensure clear guidance

Probably need to setup credentials on the backend as well to login.

I go tthis system files from another developer who stopped workng before deployment so i am not very familiiar with it either.
