IoT product development

In an effort to develop a prototype (proof of concept) for an IoT device (please don't laugh :P) where I need to:

- capture one image per day
- track GPS once per day
- monitor temperature/humidity every two hours
- monitor battery status
- charge the battery through solar panel

and

- send all this data once per day via cellular network (to thingsboard and Amazon S3 however I'm willing to accept proposals for other solutions - Azure etc., AWS)

I was thinking of using the following:

- Raspberry Pi Pico H
- High Precision RTC Module for Raspberry Pi Pico, Onboard DS3231 Chip @XYGStudy (Pico-RTC-DS3231)
- SIM7080G NB-IoT / Cat-M(eMTC) / GNSS Module for Raspberry Pi Pico
- DiP-Pi Power Master for Raspberry Pi Pico
- 5MP OV5642 Mini SPI Camera Module for Raspberry Pi Pico
- DHT22(AM2302)

After contacting Waveshare they replied that the IO resources for the Pico are too less to handle all the required functions.

Would you be willing to help with choosing appropriate hardware (available in EU) to continue on with developing the project firmware? I am ok with going a different route and using ESP32.

There is an equivalent project developed in pi zero at the moment and I'm willing to go to pico as a next step towards the custom PCB design. As a result, freelancers able to continue on with the PCB design will be preferred.

Project is expected to be awarded to proposal with most concrete BOM description, price, and previous experience.

Thoughts?
