Hello I am the CEO of ARCorp we are a new organization/company that creates Games. If you want to help create a medieval game. If you want to just comment your experience, and if we think you have enough we will send you an invite to the organization and send you the project. Good Luck!

To get people to volunteer for hard work, almost always requires that they have some kind of passion for your projects idea. You should include lots of screenshots, concept art, models rendered, sketches, something to show what your vision is for this game. Include details of the scope of the game (what all features, how many levels, how big are levels, how many weapons/items/characters) so that people know what they are about to potentially volunteer for…
Perhaps it would be important also to specify what you need done, what is done so far, how many people you already have, how experienced they are… so on and so forth.
Good luck!
