localbitcoins trust is a good thing, but not required...
they have an escrow built into website so the purchaser knows for a fact you have the bitcoin and you do not release them until their payment is marked completed and verified.... if you dont get paid dont release, if you do get paid and dont release (which im not saying you would but that'd be shitty move) they can dispute it and the site acts as mediator between where the coins go if they can prove they paid you via method you outlined blah blah blah u know how it works...
but yes I'd recommend localbitcoins and if you have been buyin there surely you've earned a "little" trust
