Hi mohal,
welcome to the Arduino-User-Forum.
Well if you want somebody to do all the programming for you you would have to ask in the jobs and payed consultancy sub-forum. Be prepared to pay quite a lot of money for it.
I estimate you don't want to do this.
If your knowedge stays on 0 this would be a very slow progressing project of remote instructed keyboard-typing.
- Doing a small step
- test
- report results
- doing the next step
repeat
with hundreds of postings.
IMHO this is no option too.
I did a quoogling and found quite a lot project-descriptions that come close to your project
but of course they don't match each detail of your hardware.

If you don't want to invest own effort in learning programming I recommend you go buying a weighing scale - ready to use - off the shelf.
Even the most professional software-developper divides such a project into multiple steps:
- install ESP32 support to arduino-IDE
- test the ESP32 if uploading code works in principle
- wiring up just the HX711 with the loadcell nothing else
- using a test-code to test if reading in values of the loadcell works in principle
- connecting the display and nothing else
- using a testcode to test if displaying data works in principle
- combining the parts of the code to do both
- adding a connection to send email or some kind of notification with a service like telegram etc.
If you are willing to learn programming you will get support here.
The complexity of this project is pretty high I estimate nobody will write down the code for this for free.
best regards Stefan
