how much do you think an end-to-end product/service like this should cost

  To come up with a clean-slate estimate would require quite a bit of work. Instead, we can walk backwards from the data we have to price the actual work. Anything below is just an out-of-my-ass guess based on experience on certain projects, experience with security validation, and what information is easily available. If we start just with development, we see that the the Github organization has 30 members. Unfortunately, the companies had absolutely horrendous source control and open source workflow practices (e.g. the android app's first commit is 35k lines), so we don't have a good history of all contributors, so for good measure let's double that to get an absurdly large team of 60 developers. Considering the pandemic, let's say they all started working on the project in January. That means that the cost of the software developers themselves is approx 30 manyears, or 3 million EUR. Translated the limited content and creating the webpages are not very expensive, but let's allocate a whopping ~100k EUR for that. We need negotiation, design and security validation as well. Let's give that 5 people, 2 months at 4 times the already expensive senior developer salary. Expensive as hell, for no good reason, apart from to cover absurdities. ~200k EUR. All these numbers are absurdly high (i.e. room for large errors), and we're "only" at 3.3 million EUR in cost. Need to add some profit margin for the company, but with more data (e.g. actual developers it took, how long they worked) the estimate could probably be pushed much lower.
