I'd recommend it to you without a doubt.
+1 to Localbitcoins
Thanks a lot but
Localbitcoins do not look like trading.
You are looking for a fiat --> bitcoin trade right? Localbitcoins is the right place for you if you want to have lower fees.
To know more about their fees -->
https://localbitcoins.com/feesBut there is also another section here in forum where you can do that trade at
Currency exchange, this is just an alternative if the fees on the chosen exchange is still high for you.
Having a P2P deal there needs a reliable escrow.
