Web App Training Assets

I have a newly-launched web application and I want to give users an intuitive, English-language orientation through two complementary pieces of content:

1. End-user guide – video format only. I will need two final cuts of the same walkthrough: one version with a clear voice-over track and a second version that relies on on-screen call-outs alone.
2. Virtual tour guide – an engaging, self-contained tour that showcases the main screens and key actions inside the app. I’m open to your recommended medium here (animated video, interactive walkthrough, or another creative approach) as long as the result feels polished and simple for first-time users to follow.

I will supply access to the staging environment, brand assets, and a concise list of use-cases that must be covered. You handle script writing, screen capture, editing, titles/call-outs, and—when applicable—professional narration.

The finished files should be delivered in high-resolution MP4 along with separate audio tracks and project source files so I can update them later.

If you have produced similar onboarding or tutorial content, point me to a few examples and briefly outline the capture/editing tools you prefer (Camtasia, Adobe Premiere, After Effects, Storyline, etc.). I plan to move quickly once I find the right fit and will be available to answer questions or provide clarifications throughout production.
