This is a free product, so there is zero investment on licenses and IDE.
Xamarin is available under several licensing arrangements. Each developer needs one license at least. To access all features, especially the Profiler, you need the highest tier.
For personal use, the Community Edition is free. If someone is a freelancer he can easily use the free edition.
Xamarin is free, or comes with Visual Studio. Therefore, it is very profitable.
In most cases, it is sufficient to have free/community license. But if you plan to seriously develop production-level, highly polished apps, you need to use Xamarin.Profiler and the professional or enterprise license.
If you plan smartly enough I think you will save some bucks for sure. You don’t need different native developers for each platform as Xamarin comes with cross-platform development so that’s an advantage.
