Hi there.
I'm certified Google Analytics/Google Tag Manager specialist and I'm ready to help you out.
For some references, look at my profile.
I went through the attached file, but it didn't make things clearer, because it was in Spanish :)
Anyway, I'm pretty much sure that I can help you to set tracking for needed event's and create relevent reports or dashboard.
For that, I will use Google Tag Manager, to set an event's and maybe Google Data Studio for
data dashboards.
Well, If you are interested, drop me a message.
Looking forward to hear from you soon.
Best regards,
Khusrav.

Sorry for typos, was writing the proposal from the smartphone
