Well, before canceling right away, just some things about it :
- Do you mean a Vocaloid based offf community with a team ? (then you need to get a voicer, a tuner, a composer, a programmer, an adult if you're minor so there can be a legal representant, an artist, etc)
- Talking about the voicer, justly what kind of voicetype are you looking for ? A mature one ? A cutesy high-pitched one ? One with a serious mid-range tone ? A male ? A female ? An androgynous voice ? Powerful ? Normal ? Whispery ? What languages will it sing in ?
- Mainly aimed at professionals, I don't think alone it'd be possible, and then if you have a team, you need to ask for YAMAHA but keep in mnid again, they prefer companies over amateur circles, even if it already happened a few times in V4 to have a Vocaloid made and voiced (or simply voiced) by someone from the fandom ; but again remember those are exceptions
- You also need a lot of money since even a simple licence for only one bank with no extras, no appends, no more languages is really costy ... And if you need it, then you'll likely have to make a crowdfunding campaing, hoping people will support
- In case your project would be accepted, you'd still need to be 100% sure things are all set up before starting, thus maybe go little step by little step
- For the voicer, as well as the artist, would you pick them directly ? Or would you prefer to submit a giant poll, even if that means a lot of work to put in the process
- As it is supposed to be a fandom, do you want it to be mostly Western community, or to even try to include other parts of it, like the Japanese part ?
And I may forget things but that's mostly what is on my mind right now
