NWR: Invitations

Anyone know where I can get nice quality invites made up online - not for a wedding, just for a party. I am not the DIY type at all and I will just totally screw them up and end up in a pile of frustration! Plus I am already behind schedule as it is.... Know any good sites? I need about 40 of them or so, and I'd rather not spend tooooo much $$

TIA!!
