Python Scraper Repair & Upgrade -- 2

I have a Python web scraper using headless browser and threading for fast scraping. It's currently unable to log in to www.racingpost.com due to their new login feature.

Key requirements and modifications needed:
- Add the login functionality to access restricted pages on racingpost.com.
- Modify the current scraper to extract additional fields of data.
- Adjust the scraping direction to optimize the process.
- Eliminate unnecessary data in the scraped output.

The primary goal for my scraper post-upgrade is to update and then create my personal horse racing database. The most critical features for this upgrade are to enable login to the site and extract more data fields.

Ideal Skills:
- Proficient in Python
- Experience in web scraping
- Knowledge of headless browser operation
- Capable of implementing threading for faster scraping
- Familiar with handling login features on websites
- Attention to detail for data extraction and modification.

I'm looking for a skilled freelancer who can address these requirements efficiently and effectively.
