HD Vector Conversion For Poster

I need my existing AI-generated art poster rebuilt as a fully scalable, print-ready file so I can run it at large-format size without any loss of quality. The original is raster-based and begins to pixelate when enlarged, so I want the artwork converted to clean vectors in Adobe Illustrator.

Once finished, I should be able to hand the file straight to a wide-format printer for anything from a standard 24x36 inch print all the way up to billboard scale, with colours and fine details holding firm.

Please recreate every element faithfully, preserve the colour palette, and supply:

• The layered Illustrator (.ai) source
• A press-ready PDF/X-1a or PDF with 300 dpi raster effects where necessary
• A high-resolution PNG preview for quick proofing

Vectors must scale indefinitely, text should remain editable, and no compression artefacts should be visible at 100% zoom.
