Explore an event identity system for a creative agency

Our agency is preparing a new client event and needs to explore a visual identity before committing to a complete campaign. The event will be used across invitations, a simple landing page, room signage, and a short presentation. We need someone who can run an exploratory design sprint using the supplied audience and brand context, propose two or three clear directions, and show how the selected route would translate into the key touchpoints. The €700 budget should result in a decision-ready concept and editable working files, not a finished production rollout.
