Gentle 2D Vector Animation for Explainer Video

I have a script and a clear visual reference ready, and I need a skilled 2D vector animator to help me bring a 3-minute explainer video to life for elderly patients. The tone must be gentle, friendly, and easy to follow, steering clear of anything too fast-paced or flashy to ensure it’s accessible for our audience. I’m looking for clean, approachable custom character designs, a full storyboard for review, a warm and reassuring voiceover, and custom soft music all coming together in a polished, HD animated video. If you have examples of similar explainer work, especially with a soft or friendly character style, I’d love to see them.
