We're building a game, and we know we can get a lot of help from the community, but is there any pros who can get just about any task done?
It's unlikely to find someone that can do anything, but for sure someone can help.
I work as freelancer for example to develop or fix games, but I also teach and do consultation related to game development.
You should at least give a general idea about what you need. So you might be contacted by the right person.
For example, I don't create plugins but I can help you with the code or game design. Another person might be more focused on the plugin creation and backend, so really, it would be better to give at least a general idea of the help you need.
