Good call on the drone!  I could go into depth on how I market my marketing business, but I don't think that's the answer you're looking for. 

Most businesses do really well with 2 things.  First, Pay Per Click Advertising and Second, Search Engine Optimization.  Getting your business in front of people that are looking for you is 15X more effective than shoving your business in someone's face.  

Pro tip -> setup some remarketing on your website so next time a prospective customer watches that drone video and thinks about it they are reminded :)
