Nice fees you have here
Considering that you are a newbie (your first post is here) ... I think the scam attempt is obvious.
Its obvious indeed and no one would fall for this and using or stating nice fees to lure out people but still in a big "NO". Newbie account and doesnt mentioned about escrowing the funds and he just directly said about the service.Just have read post above why we should use this if theres localbitcoins.
"nice fees" it was a joke
20% is a huge fee for a simple exchange!
For example I charge only 9% and I'm an trusted member of the forum.
