Have C# web scraper. Need it updated and ready for beta.

We have a system that allows a user to scrape all linkeds account information based on a selected Keyword. The system consists of two basic modules: desktop application and a registration website. The registration website will allow user to register for the application. Once they login with one IP, that user is locked to that MAC for both trial and the paid version. The application will allow the user to search via a linked sales navigator link - copies from the Sales Nav. Problems: The system needs a good look over. Current registration website is in .asp, we need it converted into PHP so user can register. Scraper process is divided into 2 sections Need to make sure the Stripe integration is working and correct. Scraping is divided into 2 parts. 1. It scans linked and grabs urls 2. It visits each URL and grabs the public information from it.
