You don't need to gauge the interest from this community. Of course this community is hungry for any
source of funding and people. The problem isn't getting devs interested. Your real problem is whether
your new site can attract people who'll donate money.

ABSOLUTELY, if you create a site for devs to get funded, you'll be flooded with interested devs and
project submissions.
ABSOLUTELY, if you create a site where aspiring artists and aspiring programmers can seek paying work,
you'll be flooded with resumes.
These are not questions that need to be asked.

But how are you going to prove your ability to deliver on the expectations of devs, artists, programmers,
and investors? How will your site's submission policies differ from those of Kickstarter and Patreon et
al? That's the thing you need to concern yourself with.
