this approach doesn't seem to be working for you. I am not saying this because I think no one should ever try to create something new on their own. I just think it's much less likely that you will come up with something successful on your own. Particularly based on how your examples have been halted by lack of awareness and ignorance to how the industry works. Working on this side of the industry will give you a better idea of where there are needs for innovation, and how you could provide that, while avoiding needless setbacks because you don't know about basic things that are happening.
Most successful new projects (not produced by some previously existing large industry entity) seem to have better insight either directly because they are headed up by performers, or they have taken the time and done their homework getting all the needed information from performers--when we are willing to take OUR time to share with random strangers who want to make money off of our work, so let's add consultation fees to the list if you're really serious. A more direct route would give you the best odds at a profitable outcome. Know what I mean?
If you are able to establish yourself as someone beyond random internet stranger #1097413, then you might get better responses to your inquiries. But it's asking a lot for nothing in return when you just show up to a community you don't participate in like this.
