Hello, Dia,
“Unpaid” until the “future” is not a model that works.
More than likely, if you do get programmers, artists, composers, etc., they won’t be very good, and your project won’t sell or be successful.
I STRONGLY encourage you to either:
- Gather the funds first
OR
- Continue learning Unreal so you can see how many of your ideas are easily implemented.
Preferably both.
Don’t put the cart before the horse.
(One more thing of note: You need to keep in mind that others will not be as invested in your project and vision as much as you are. Even when you’re paying them.)
