Custom Carrier Board Design and sample for Raspberry Pi CM4

I am looking for a freelancer to creating a custom carrier board that is specifically designed for Raspberry Pi Compute Module 4.

Features:
- It should include an Ethernet
- Type-C USB port power power.
- We're also looking at equipping it with a 4G mobile module (SIM7600 or equivalent that work in Australia/Telstra).
- 1 X Sim slot.
- 2 X External antenna connectors SMA
- 1 X Power LED for CM4
- 1 X Activity LED for CM4
- 1 X Multicolour LED for signal strength of mobile module.
- The carrier board should be made as small as possible.

Skills and experience:
- Freelancers interested need proficiency in electronics and PCB design, along with a deep understanding of Raspberry Pi Compute Module 4. Experience in custom carrier board design and SIM7600 or equivalent 4G mobile module that works in Australia on Telstra also required. The freelancer would be expected to have sample units manufactured and tested for functionality (third party manufacturer ok - Cost will be paid by me).
- Applicants able to design user friendly configuration of the mobile module would be highly desirable.
- Any applicant able to also design an enclosure for the board would be highly desirable.
