All the 4 points are covered by our service. The workflow looks as follows: You login at wpdemo.cloud, create a template, customize it as you wish (install your product etc.), click 'Update Template' button. Now you can either directly redirect your customers to the demo link or ping our API from your site to request a demo. And yes, there are no collisions. Each demo request gets a fresh install of your template and each demo instance has its own codebase and database. Unused demos are also garbage collected. Again yes, you have access to file uploads, admin capabilities etc. You can basically have root access to the WP installation, since it runs inside a docker container. Let me know if you still have questions.
