My advice is to get one.
You are going to need a paid licence because the trial is just a trial and you cannot use a community licence for this.
It sounds like its out of your depth and I don’t think someone can give you the level of detail you require you need to do this yourself (plus your trial will still run out).
I’d also advise you to remove some of those screenshots as they contain customer data and contact info. Whilst not personal so I think technically not against any laws, if I were a customer and saw my work orders posted on forums I wouldnt be happy.
