Vectorize Outdoor T-Shirt Illustration

I already have a hand-drawn sketch for a new T-shirt and just need a skilled illustrator to polish and convert it into clean, print-ready vector art. The final style should feel like REI-inspired cartoon concept art—playful yet outdoorsy— with scenic landscapes taking center stage exactly as I’ve laid them out in the sketch.

Here’s what I’m looking for:
• Trace and refine my rough lines, keeping the overall composition intact.
• Add any small finishing touches that enhance the outdoor vibe while matching my references.
• Deliver a fully scalable vector file (AI or EPS) plus a high-resolution transparent PNG ready for screen printing.

I’ll send a picture of the sketch immediately after we start, and I’m happy to answer quick questions or give one round of feedback before final delivery. If you’ve handled T-shirt graphics before and can match that REI aesthetic, I’d love to see a couple of samples from your portfolio.
