Mr "Alin",
Although we're from the same country (based on your nickname) , I will write in English for the other users to understand:
If you want to really do these trades go on LocalBTC and publish some ads. At first it will be hard, but in time you might gain some feedback and it would be easier for you to find more users.
I don't recommend exchanging anything on his 'professional' website. We've all seen too many scams.
First, prove you're reliable and maybe then you can say your service is "SAFE". Until then, you have no chance.
Think! Who would be idiotic enough to trade his irreversible bitcoins for a reversible payment method with an user without any feedback and/or reputation?! And with an outrageous fee ? Haha.. No.
All the best.
