I am looking for a Facebook Pixel expert

Hi, i am looking for a Facebook Pixel expert who can install my Facebook Pixel on my website so that it works 100%. I want to end up creating a campaign on Facebook and the leads (registrations) should be tracked. The whole thing needs to be done remotely, Since I can not give my Facebook password. I already have a Facebook Pixel installed on my site, but somehow it asks for an API and subdomain, etc. This became more and more and way too complicated for me. Therefore I need your support. So this is the thank you Page after the user here on this site the pixel should fire:
