Precision Bézier Vector Tracing of 60 Nail Plates

I am looking for an experienced vector artist to create precise, editable Bézier outlines of the visible nail plates on 12 fixed hand-template images (see one hand-template attached).

Each image contains 5 visible fingernails, giving a total of 60 individual nail plate outlines.

This is precision tracing work, not creative illustration. The objective is to follow the actual visible anatomical nail boundary as accurately and smoothly as possible.

Requirements
Work directly on the original 1254 × 1254 px images without changing their geometry, dimensions, position or alignment.
Create one separate, closed vector path for each nail:
thumb
index
middle
ring
pinky
Use clean, smooth Bézier curves with as few control points as reasonably possible.
Follow the actual visible nail boundary precisely at:
cuticle / proximal edge
left sidewall
right sidewall
free edge
Do not beautify, symmetrise or redesign the nail shape.
Automatic tracing or AI-assisted tracing may be used as an aid, but automatic output will not be accepted as the final result. Every path must be manually checked and corrected.
Final paths must remain fully editable.
Deliverables
60 individual, editable closed Bézier paths
SVG files preferred
Original editable working file also required, for example:
Adobe Illustrator
Affinity Designer
Inkscape
or an equivalent professional vector tool
Each finger/path must be clearly named.
All vector paths must remain aligned exactly to the original 1254 × 1254 source images.
Selection and quality control

Please include examples of your existing precise Bézier/vector tracing work in your portfolio or proposal.

After selecting a freelancer, the first step of the project will be the completion of one nail plate from the supplied sample image as a quality checkpoint.

I will review:

anatomical boundary accuracy
Bézier curve quality
smoothness of the path
appropriate number of control points
accuracy at the cuticle, sidewalls and free edge
exact alignment with the original image

If the required quality standard is met, the freelancer will proceed with the remaining nail plates.

Please quote a fixed price for the complete set of 60 nail paths.

Please state in your proposal
Your fixed price for all 60 nail paths
Which software you will use
Your estimated turnaround time
Please attach or link examples of precise manual Bézier/vector tracing work
Optional additional work

I may also require 2x12 additional hand-image variants with 2 different skin tones, based on the same 12 original templates.

These variants must remain geometrically identical to the originals. Only the skin appearance may change.

The following must remain unchanged:

hand shape
finger positions
nail geometry
image dimensions
canvas position
alignment

If you have strong photo-retouching or colour-grading experience and can make these skin-tone changes without altering geometry, please quote this optional work separately.
