Elegant Event Promo Poster

I need a single, eye-catching poster to promote an upcoming event on social media. The visual mood must stay elegant and formal, yet still compel viewers to click, share, and ultimately attend. Because it will live entirely online, the design has to be optimised for Instagram and Facebook feeds—crisp text at mobile resolutions, balanced spacing, and colours that look refined on-screen.

Here is what I expect as the final hand-off:
• A layered source file (PSD, AI, or Figma—whichever you prefer) so I can update dates or speaker names later
• A ready-to-post JPEG/PNG in both square and story dimensions
• All fonts either outlined or linked to free licences

I will supply the event logo, copy, and any brand guidelines as soon as we start. Please share a small portfolio sample of past elegant or corporate-style posters so I can be sure our tastes align. I’m ready to move quickly and can give feedback the same day you deliver the first draft.
