Conversion tracking setup through Google Tag Manager

Please note, this task requires good knowledge about setting up conversion tracking using tag manager. We want to track user actions on user journey so we need to set that up in Google Analytics, Google Ads and we need to set up facebook pixel conversion tracking. We have already implemented a big part of this but we need an expert to come in, do proper testing together, add + fix the missing things and make sure that everything is working and being tracked.
