3D Design of Posture-Correction Device

I am looking for a Product/Industrial Designer to create a professional 3D design and technical presentation for my wearable posture-correction device, “Posture+”.

About the product:
Posture+ is a small, lightweight wearable device designed to be attached to the upper back/clothing. It detects poor posture/slouching using an IMU sensor and provides vibration alerts. The device is intended to have a compact, premium and comfortable form factor.

What I need:

Professional industrial/product design for the physical device enclosure
Compact, lightweight and ergonomic design suitable for wearing on the upper back
Premium modern appearance with smooth rounded edges
Design should look like a real consumer electronics/medical-wellness product
Proper space consideration for PCB, battery, sensors, vibration motor, USB Type-C charging port, button and other internal components
3D CAD model of the enclosure
High-quality realistic 3D renders
Top, front, side, bottom and back views
Dimensioned/technical drawings similar to the reference images I will provide
Different design angles/views for presentation and pitching
Final files should be suitable for 3D printing/prototyping and future manufacturing

Reference:
I will provide reference images showing the style, presentation and level of detail I am looking for. I want the final design to be inspired by the overall quality and presentation of the references, but not copied.

Preferred freelancer:
I would strongly prefer someone based in Delhi, Gurugram, Faridabad or nearby NCR, because I would like to have at least one face-to-face meeting to discuss the product and review the design/prototype.

Please share your portfolio of product design, industrial design, wearable devices, electronics enclosures or similar projects along with your quotation and estimated timeline.
