I will do vector tracing work

In computer graphics, vector tracing is the conversion of raster graphics into vector graphics. Raster graphics are represented by a dot matrix and often appear pixelated. Vector graphics retain all the colors and contours of shapes and lines, and so are more desirable for graphic design.

While a raster image may look good on the screen, it does not scale well and will look distorted if printed. On the other hand, vector images scale easily without any reduced resolution, which is why they are the preferred file format for printing, both on paper and clothes.

Vector tracing, which is sometimes referred to as vectorization, can either be done manually or automatically. Vectoring an image manually means that the conversion is done by hand (“hand tracing”), and works best for simpler graphics without a lot of curves or contours.

Once you've identified a pool of candidates based on skills and availability, look at their experience and browse their gig gallery. Look at samples of previous vector conversion projects to get a sense of their work.
