I have spent maybe 100 or 200 bucks on various third-party game assets and tools over the years, and my build server costs me 6 bucks a month. I work on my games in my spare time while working a full-time job, so I do not have any labour to factor in.
This is going to get me insulted again but you should look at your failed crowdfunding campaign and seriously consider how much more money you want to throw into your project. You're extremely unlikely to recuperate that cost, to be honest, and if you do not have income outside of your game, you could end up in a very nasty financial situation.
