Unity 3D game Server setup/ WebGL build assistance needed!

Hey there! My name's Dom. I'm an artist building a game that will allow me and ohers to view and interact with my art in a unique way. I'm looking to fill 3 roles for my new Unity game that is in V1 Alpha version. Please watch this video (It's decently short and pretty much explains everything). Please pay particular attention to role # 3. [login to view URL] I'd like for you to let me know if you're interested in the role of Server setup and WebGL build assistance. I’ll need help designing and executing where I should upload my game files and eventually user data on the cloud. Azure or AWS? Please be able to talk me through the pros and cons of these services in terms of cost, ease of access, and data security. After we make a decision, I’ll execute in setting up the server. Then I’ll need guidance in accessing the game through my site via WebGL. Please have experience uploading and accessing web based Unity games through WebGL so that it can run seamlessly on desktop and mobile. I will require simple documentation for how to upload new iterations of the software and manage it.
