POS App Demo Video Creation, UI mockup screenshots, login screen image editing

I'm seeking a skilled professional to create a product demo video for our POS application, using screen recording. The video will be used on our website and marketing materials, so it needs to be high quality and engaging.

Key requirements include:
- Record and edit a high-quality screen recording video demonstrating the UI and core features
- Help create a script or storyboard
- Highlight the following key features
- User interface navigation
- Transaction process
- Reporting and analytics

Additionally, I need:
- Mock Data Generation and UI Mockup Screenshots (application, website)
- Populate the POS system with realistic-looking mock data (e.g., sales records, users, transactions)
- Capture and deliver polished screenshots highlighting different UI parts for promotional content

- Edit Existing Login Screen Image with realistic-looking data
- Modify an existing image used on the login screen to reflect updated branding or design elements.
- Change background elements, adjust colors, or update icons/text to align with our visual identity

Ideal skills and experience:
- Video editing and screen recording expertise
- Graphic design proficiency
- Experience with UI/UX mockups

What is expected from you:
- Create the data in the system (you will be provided with login credentials)
- Basic storytelling/video editing sense
- Capture UI Screenshots to be used on the website (one through the App, one through the POS web-app)
- Edit the existing login image to match current features/design
