Hello,
I have prepared a sample of 20 civil engineering businesses from Berlin, ready to be sent to you. Please request it via chat so I send it to you and you don't have to pay for it elsewhere.
They all have the required data and more - business name, physical address, website, email, phone number, main business category.
If we were to work together, pricing would be 0.5 Euro/lead, so my hereby offer includes 1500 companies. I will be able to send you this list of 1500 businesses in 2 to 3 days.
Best regards,
Mihnea
