Need assistance/admin on Shopify-GoogleAds-GA4

Long running Shopify store, require assistance on debugging our Google Ads / GA4 admin, to make sure conversions (specifically purchases) are being tracked correctly. Want to cover any possible cookie consent issue that might create gaps in tracking too, so might require multiple tags or some server-side setup rather than just 'out-of-the-box' tag setup.

Have had a go myself but it's a minefield of settings, so would rather get an expert in to debug and make sure we've got it running smoothly.

Please be prepared for me to ask questions throughout! Potential for longterm partnership, to have some sort of monthly retainer of services going forward.
