My sister took this advice and a number of years ago started her own company - Bliss. She does amazing work (and I should know since she created our gorgeous wedding invitations!).
She just e-mailed me with some good news - her business has been featured in Wedding Guide Chicago! Check it out: http://www.weddingguidechicago.com/modules.php?name=GreatIdeas
She does more than just wedding invitations. Go to www.blisscards.net and see all of her custom-designed, completely original, and all handmade invitations, stationary, albums, journals, etc.
