Most local businesses who say they tried advertising boosted a post. Nobody wrote it, nobody filmed it, and nobody looked at the numbers afterwards. That's a different job from a scripted campaign with creative made for it and somebody pacing it daily.
Metcalf Media builds campaigns around the service area you actually cover and the jobs you actually make money on, running against video shot at your business. The ad account stays in your own Business Manager, the platform bills your card directly, and the fee is flat — no percentage of spend, because percentage pricing pays an agency to recommend a bigger budget whether or not it's working.
Advertising is worth starting above roughly $750,000 a year in revenue, with somebody able to answer the phone when it rings. Below that a website does more good than paid traffic does, and you'll be told so.
