Professional Photo Vectorization for High-Quality Large Format Printing

We are seeking a skilled graphic designer to convert several pixel-based photographs into high-quality vector graphics. The primary purpose of this conversion is to enable printing of these images at a significantly enlarged scale, specifically 10 times their original size, without any loss of quality, pixelation, or degradation of detail. The ideal freelancer will have a strong understanding of vectorization techniques and the ability to produce clean, sharp, and scalable vector files suitable for large format printing. Please provide examples of previous photo-to-vector conversion projects in your proposal.
