Image Enhancement for Laser Engraving

I need two PNG images edited for laser engraving. The images must be enlarged to 35cm height and 20cm width while retaining the clarity of fine lines and patterns. Ultimately, the images need to be converted into a high-quality vector format to ensure scalability and precision during the engraving process.

Ideal skills for this job:
- Proficiency in image editing software (Adobe Photoshop, Illustrator, etc.)
- Experience with preparing images for laser engraving
- Ability to maintain image quality during resizing
- Expertise in converting images to vector format
