Teach a man to fish, and we can all go to the chippy after work.
But forget the bait and we'll eating our shoes like Charlie Chaplin.
Think of video testimonials as bait, and Google Ads 'experts' as the fishermen.
The better both are, the more you'll catch.
Good fishermen don't come cheap, so not giving them good bait if you have it, or will have it soon, is plain crackers.
A load of old cod as you say.
But if you have a decent video testimonial, then it could be worth finding a Google Ads expert.
They could hook some decent fish (clients) with that bait.
And with their service fees, you could invest in SEO, mailing lists, social media, and other awesome things that pay for themselves many times over.
