Looking for a Meta Ads Specialist for Our Dropshipping Store

Our online dropshipping store needs a Meta Ads specialist. Our Facebook Ads website and account are already ready, we make video ads for our products, and we also receive a few orders per day thanks to our Facebook Ads ads. But the results in advertising are not very good for me, so we need a specialist who will make advertising companies for us with a ROAS of over $ 3 in at least a short time. Respond only to those who can GUARANTEE it.
