Financial Data Scraper for 1-Minute OHLCV Data

If this task can be completed, along with payment I will provide a very positive review along with potential future works with higher budgets. So I am looking for an experienced scraper/data engineer to collect 1-minute OHLCV price data through ChartExchange for roughly 5,000 stock tickers, ideally going back up to 5 years where available. Required fields: Open High Low Close Volume Timestamp The data should be pulled from ChartExchange chart pages, using the ticker URL pattern. For example: https://chartexchange.com/chart/nasdaq-aapl/ The chart should be set to OHLC and 1 Minute data. I have a list of the roughly 5,000 tickers that would need to be swapped into the URL in place of aapl. This will be a large-scale scrape, so I need someone skilled with batching, retries, rate-limit handling, clean storage, and reliable CSV/Parquet output. Please apply only if you have experience with large-scale financial data scraping and can deliver a clean, scalable, well-organized solution.
