Hey girlie... In your other post, you said you were looking for cost effective ideas on save the dates, invitations, decor, etc.
Invitations/Save the Dates - consider using a rubber stamp for your design. Simple and cost effective with a big wow effect!

Good resources for paper:
Florals - A lot of girls on here are doing artificial flowers (including myself). Hobby Lobby and Michael's have tons of options and a pretty wide selection of real touch flowers as well, if you're concerned with the quality. www.save-on-crafts.com also has a good selection, and so does www.afloral.com.
If you're still looking for a caterer - MyChef, Chef Paul, and Schaul's Cuisine are all affordable (and yummy) options.
DJ - my guy - Big Don Kaminsky is great. http://www.xl-entertainment.com/ I've read nothing but good reviews on him from The Knot's Chicago board, and my experience with
him so far has been wonderful. He's also from Indiana, so his prices are a little lower than the Chicago guys.
Cake - my girlfriend had her wedding cake made by Jewel. It was delicious and looked fabulous.
