Information gathering

It is required to compile a database (name of the organization, address, email, phone, type of activity), all this is to enter into the Exel file, 500 contacts - one hundred rubles! 5,000 contacts - 1,500 rubles! We need road construction organizations. Try to find 10-15 organizations (arbitrarily) and then write if you like.
In more detail, only those who try to find at least 10 contacts and understand what kind of work this is.
