scraping for local residents phone numbers for cold calling -- 2

Hello We're looking for a company to find customer leads for our business. We run a small heating and cooling company for residential homes. We are wanting to generate a call list of a 25km area around Kelowna. I was told these leads are called B2C leads? Im wanting to scrape the web and collect phone numbers of homes in our area that we can call for potential work.

Looking forward to hearing your bids
