I don't want to break rules and I couldn't find any useful information if it is possible to post here for hobby project recruitment.
No, you can't. But thanks for asking first :)
That's out of the scope of gamedev.stackexchange, and Stack Exchange at large.
The Stack Exchange is a question and answer site; so, as already stated, it is not an appropriate platform to post job recruitment.
On one side, you could seek out forums. However, it is entirely possible that you specifically wish to ask our users, whether it be due to previous interaction, or previous answers they have posted.
If that is the case, you also have the option of directly chatting with users you would like to work with in chat, once you have earned the requirement of 20 reputation points.
