Explainer video with animation motion graphics, Greek voice over

We are a SaaS company in the hospitality industry, and we are looking for a professional video creator to produce a short explainer video for one of our product features.

The video will explain a feature called "Communicator", which helps hotel staff manage guest communication from multiple channels (such as Booking.com, Airbnb, Expedia, and WhatsApp) through a unified inbox inside our PMS (Property Management System).

The video will be used inside our PMS software and will target existing customers as part of an upselling campaign.

Below you will find a reference video from another feature of our product to help you understand the style and level of production we are looking for.
