Python Selenium Need Code to Automatically Update chromedriver

I have a Python program
which is a ad submitter.

It uses chromedriver and selenium

I have compiled it into a exe
(pyinstaller --onefile pythonprogram.py)

My problem is that Chrome updates and
then I need to manually update chromedriver
every time.

I need the program coded to update
chromedriver automatically.

It needs to:

1. Check the version of Chrome browser
2. Check the version of chromedriver
3. Download and install the correct version of chromedriver
in the executable folder.

Also if no chromedriver is present then
download and install the correct chromedriver for
the Chrome browser.

I can pay $100. for this job.

Thank you.
