We got very lucky! The guys who I started the business with previously worked for another company. There clients followed them to us, I worked my butt off on SEO the first few months and got us to the first page of google, and then the almighty Facebook has blown us up. We have about 4,000 likes all from our service area, Las Vegas and Henderson, so we promote quite a bit on there.
Also the other methods of door hangers and all that BS.. We just went full blown and then we just started working off referrals and didn't have to do much advertising anymore. We are also in Vegas and Henderson where there is over 2 million people, I'll be impressed when we make it to 10,000 houses.
Or be like that guy in Virginia that is suing yelp and do 29,000 houses a year lol
