MacOS App Development for Adult Site Scraping

I'm looking for a talented web scraper expert who can create a MacOS application for me. This app should be capable of scraping content from an adult website. The specific content that needs to be scraped includes:

- Videos
- Thumbnails
- Video names
- Categories and probably some more info

The format for the scraped data hasn't been decided yet, so your expertise in this area would be appreciated. It could be stored in a variety of formats such as CSV, JSON or XML.

This project is for personal use, so the app needs to be user-friendly and efficient.

Ideal skills and experience for the job include:
- Proficiency in web scraping
- Experience in MacOS app development
- Knowledge of data storage formats
- Understanding of user-friendly application design.

I would prefer someone who can understand my needs and can suggest the best practices for this project.
