You're going to be paying a pretty high premium to use one of those sites such as LBC or Paxful, which I do highly recommend as you're not going to be scammed on those sites. I think paying the premium is well worth it in order to use those sites.
As being a former seller on Paxful, I've noticed that the amount of BTC you're going to be getting from the seller (percentage wise) is going to depend on the time of the day in which you iniate the order. So, go on mid-day for people in the US as that's usually the best time to go and save the most money.
Coinmama, Cex.io and Virwox are all good service for this.
Aren't you going to need to be verified for all these?
