On the development side: I'd go for firebase, frontender myself and the docs are pretty easy to follow. Since you know angular, you can use angularfire to easily get you started. If you have experience with yeoman you can try out this generator (https://github.com/dsimard/generator-angular-phonegap https://github.com/dsimard/generator-angular-phonegap) which gives you an emulator to phonegap. Didn't try it myself, but seems interesting. On the projectside: Cool that you would take your time and skills to work on a project like that. I had the sad experience of losing someone close through suicide, so... yeah. Thanks.
