Everything starts as newbie and good thing is you're asking for opinions.
Thank you so much for your encouragement. What I learn so far regarding escrow is that first I have to get trust of members here by doing some trade and getting +trust. Building reputation that's displayed with profile is important.
So if you can answer my another question i.e. how to do p2p trading with people of high ranks and wh forum is right place for that.
No worries, this is a forum and we discuss ideas and opinions. Yes, trust/reputation on trades with other users is the basis if you want to start an escrow service. Sometimes it takes time and people on the circle of your trust to get that green trust though. You can check this general board of
Marketplace, it's where you can gain this trust if you're into p2p trades and escrow but it isn't limited in here because you can gain trust on other boards for example your local board if you want to start your service/s there.
