generate a list of B2B sales lead

Hi, I'm looking for a sales list of leads on online course providers. I need the name, email, and contact number of Edtech companies with an online course but do not have a proper community. To be exact, I need online course providers. The courses must teach content that is freelanceable. Like digital marketing, application development) (Example: the product house, digital Deepak, etc.)

I'm looking for EdTech companies with online courses that have at least 300 students.
location: India
It would be great if you could provide a sample work while contacting me
