Are you alright? What kind of statement is this? He wants to do an exchange but should stay away from exchangers? Do you even know what an exchanger is?
If you want to exchange for free, you need to find someone who need LR $ exchanging frm AP $ Exchanging sites always takes fees
You might want to consider the forum exchangemoneyforum.com. In the past I have done some exchanges with the user topearn, he is the person having the most succesfull trades in this forum. I bet he will not scam you.
You may try Allcurrenci.co.cc for your exchange. They have a variety of currencies which makes it flexible for a client Allcurrenci.co.cc
yeah it is risky to exchange but there are also some good exchangers you should consult it in the moneyexchangers forum..
