T-Shirt Image Enhancement & Vectorization

I need a small image modified and enhanced to high resolution for t-shirt printing. The image may need to be vectorized to ensure scalability for different shirt sizes.

Based on the Superman shield, replace the "S" with a simple clean stylised "M"

Requirements:
- Color correction
- Adding elements
- Removing elements
- Vectorization for scalability

Current file format: JPEG/PNG

Ideal Skills & Experience:
- Proficiency in image editing and enhancement
- Experience with vectorization
- Familiarity with t-shirt printing requirements
- Ability to work with Adobe Illustrator or similar software
