Convert JPEG for Redwood Engraving

I have one artwork in JPEG format that needs to be re-created professionally so it engraves cleanly on an 18" × 8" piece of redwood. Please convert the file into a CorelDRAW (.cdr) document and also supply a 300 dpi JPEG at the exact final size. The graphic will be sent straight to the engraving shop, so it has to be sharp, properly scaled, and free of pixelation or stray nodes.

Deliverables
• CorelDRAW (.cdr) file, sized 18" × 8"
• 300 dpi JPEG of the same dimensions, ready for production
