Yeah, sounds like you are hoping to work as a community member for a website. You should post in the services section for that.

If you want to collaborate by investing, I believe there are a few sites which are still taking investments for increasing their bank roll so they can expand their site and increase the maximum bet sizes which attracts large bank rolled players to their websites. Just be sure to do your due diligence before you go investing, because many similar sites have shut down in the past.
