Stress test an angular/ionic site, probably with protractor & vm's

We have built an angular 7/ionic 4 application using google firestore and firebase authentication. We want to load test the entire platform, end-to-end, simulating 50 users/second signing up, saving their profile, and navigating the application. We are open to suggestions about the best way to accomplish this, but are thinking that this would best be done with protractor and a headless browser running in VM's, such as AWS or Google Cloud, so we can spawn more VM's until we are simulating the desired load. The deliverables are: 1. We will give you the URL of the website and the workflow of what to test. It will be simple. It will consist of 1) signing up to create a new account, 2) saving some dummy data in the profile page, 3) logging out, 4) logging in, 5) using the menu bar to visit 10 pages on the site and, 6) and on one page where we have a list of photos clicking 'thumbs up' and 'thumbs down' on 4 of them. You will tell us what tool to use and what VM's you want, we will pay for the licenses or provision them and give you the credentials to access them. 2. Create the test sequence and the scripts or VM images 3. Scale up the VM's until we hit the desired load and give us step-by-step instructions with screenshots, so we can deploy and repeat the tests later.
