I have database of about 150 million b2b contacts which I want my clients to access the data by login to a website .
Database rows - Name , title, email, phone number, company name, company details, etc, about 23 rows.
I want my clients to access this database by paying and accessing the database with search criteria’s like name , company name, title, industry , etc.
I want the website to load the details fast .
Let me know if you can create so that I can explain in detail.
I need a developer who can speak to me over phone so that I can explain things in detail.
