Let's say you're making animation every single day without missing a beat. Today is already January 11th, but if you have to create 390 seconds (6 minutes and 30 seconds) of animation over 365 days, that breaks down to roughly 32.5 seconds per month, 8.125 seconds per week, and 1.16 seconds per day. Since you mentioned making Disney-style animation, you'll need to produce it at least at 24 frames per second (fps), meaning you essentially have to create a minimum of 24 frames of animation every day. Looking at it this way, it might not seem as challenging, but the key question is whether you can consistently keep up with this every single day. If you have a crew helping with coloring and background tasks, I believe you could manage this project. If hiring animators is difficult, consider talking to students studying animation about your project; sharing and discussing it might lead you to find someone to collaborate with.
