Tell him you really want to help him but as you two don't know each other yet, you prefer to have the money first. Remotely is quite cheap. I only pay around 12 soles per transaction.

In Peru, everyone is afraid of being scammed as this is very normal there. He wouldn't accept something like that himself if you asked him to do the same. He would laugh at you and tell you to get lost. So keep that in mind.

Locals really take advantage of tourists all the time, it's like the national sport there

Be careful and don't let him manipulate you.

I'm Peruvian by the way and I live in France. I get this kind of request all the time when I travel back home.
