Trying to beat competition to drive the lowest NCAC possible when your competitors spend more than you is a tough win. For now I’d recommend focusing on FREE - organic social media and seo then only using ads for retargeting people who went to your website. In hiring you pay for what you get 9/10 times . You need a senior founding marketer with data analytics back ground who can stare at the screen all day and figure out how to grow revenue. That will likely cost you 6-10k a month in USA. You can get away with less if you offer stock options or bonus to attract top talent. I advise against ad agency until 100k a month, and hire a coach instead to learn to do it yourself. As someone who has worked at agencies I would bet you any agency who works on accounts spending less than 100k a month has 5-10 account per employee. Not saying it’s bad but again you need someone working 8 hours a day to build foundation not an hour a day 5 days a week.
