DIY Wedding Mentor, a fellow start-up company is offering "Weddings-in-a-box!". You can choose which package you would like to see at your wedding for low cost. The owner of DIYWM, hired me to design 3 seperate invite packages. Each has a different feel: rustic, sweet/floral, and classic. They include a save-the-date, invite, menu, rsvp card and program. DIYWM makes it easy, you just send in the content you wish to see on what package and all of the designing is already complete- they will personalize your invite package for you.
