Yes, it’s always worth investing in some professional help. The good news is: it’s very difficult to "crush the whole thing" with a Google Ads campaign.

The easiest way to fail on GAds is to waste money. Be ready to spend $100/day for ~2 weeks in order to see some real results— either good or bad.

But even still, hiring a pro to give it a look would be a great way to ensure your settings and campaigns are configured optimally. I'd expect to pay $50-100/hr for that person's time.

I don’t provide this service but I could definitely connect you with a few folks who do, if you’re interested.
