Create a Facebook Campain.

We need to set-up a working facebook campain for our cloud based rendering service.
We want to start with a simple goal which is the free registration to our service and the download of our application.
We want to start with a single city which is London. Our target are Architects only.
We need to archive the lowest possible facebook cost x registration.
Stats are tracked with Matomo. We do not want to use Google Analytics.
