Hey Ladies!!

I'm having my ceremony in Ocala, Fl at Shalom Park (ourdoors) on April 16, 2011, mid-afternoon (2pm). We are on a REALLY tight budget (think basically $0 - $1500). My dress is Ivory, my BM's are wearing chocolate dresses with champagne sashes. Other accent colors are sky blue and sunflower yellow. I'm a relaxed, sunshiny, smiley kind of person; but I'm not very savvy with planning food or flowers.
The problems I'm having are this:
What kind of food should I serve at the reception? I was thinking that hors d'oeurves would be best, since a full-blown meal would be more expensive. But what should I serve? Remeber: cheap is better!
And...
I still haven't found a florist, but I also don't know what flowers I want. My favorite flowers are daisies, wildflowers, and roses. I love the idea of a hand-tied, homemade bouquet, but I'm getting resistance from my mom on that... Are there any flower-savvy people out there that can help me? Remember: cheap is better!
I really, really, really appreciate any help that you can give me! If you have pictures, that would be even better! I feel like I have scoured the internet and still not learned a thing.
Love, trust, and pixie dust,
