Love the Sophia invite from le poetik studio on Etsy! It's perfect for an evening wedding with a hip reception at a steakhouse or downtown loft.
For $50 they will create an invitation, rsvp card, reception info card, and accomodation card plus customization and 2 revisions per card! Once you receive the file you can print your cards online here. This route takes a bit more DIY, but a lot less cash!
