Data Mining: 15,000 Indian Real Estate Agencies

I'm seeking a data expert to compile a list of at least 15,000 real estate agencies from across India. The data needs to include the contact details, specifically the email addresses and website URLs of these agencies. The ideal professional for this task should have strong data mining skills and experience in collecting and organizing large datasets. Familiarity with the Indian real estate market would be an advantage. Please ensure the data is accurate and up-to-date.
