Construction & Real Estate Lead Database -- 2

I need a fresh, fully verified database of businesses and professionals active in the construction and real-estate ecosystem, but for Mumbai and Navi Mumbai. My focus is on four categories: Architects, Chartered Accountants, Builders & Developers, and Advocates.

For every record I must receive:
• Company or firm name
• Contact person’s name and Number
• Full office address
• Office Number
• Email Id

Please scrape, cross-check, and clean the data so it is current and accurate before delivery. The final file should arrive in either Excel or CSV format; separate tabs or clearly labelled columns for each category will make review easier.

I will spot-check a sample on receipt—records with unreachable numbers, bounced emails, or outdated addresses will need replacement. If you already maintain high-quality sources or proprietary scraping scripts, let me know; efficiency is welcome so long as the end result is reliable.
