Has anyone utilized the QSBS Section###-###-#### rolling over QSBS qualifying stock sale proceeds into another QSBS qualifying entity to eliminate capital taxes tax if held for a cumulative of 5 years)? Where can I find available QSBS companies or investments to roll over into?

The 60 day timeframe is extremely fast and I'm surprised there aren't any brokers/marketplaces catering to this situation. Google and my accountant were not able to outline how these deals happen in reality, they just discuss without any practical context on how to execute. Thanks for any leads or practical deals you've seen.
