Develop a database of event agencies

Good afternoon! It is necessary to make a database of event agencies in Moscow (name, website, telephones, emails, office addresses). Where to get information: Text verborgen (select only event agencies and only Moscow, sort by rating, make the first 1000 agencies with the highest rating). Contact data is not taken from the site Text verborgen, and from the sites of the agencies themselves (often the information does not match).
