Facebook Tracking + Google Tag Manager Expert Needed ASAP

Looking for a facebook tracking expert to help resolve issues that are appearing on my conversion campaign. I've already done the bulk of the work and have everything setup with server-side tracking and have the tags created in google tag manager, but now receiving some errors with event deduplication I'll need resolved, also receiving an error message saying my domain needs to be verified, even though it already is.

Please note that this is a very urgent project, so if you are applying please be able to get started today. Please send me a quick message and tell me about your experience with conversion campaigns on facebook and google tag manager. Thank you!
