Needing some advice/ help regarding decorations for a wedding in the park!

My fiance and I are getting married in the park! We are not allowed to have certain items like sparklers, balloons, or confetti to name a few. My vision is having "ribbon wands" on all our guest chairs for the ceremony. As we walk down the aisle as husband and wife everyone will wave the wands around and there will be a sea of ribbons floating everywhere and bells chiming. We'd also use them for our grand exit!

I have dowels, bells, and a little string to tie the bells to the top dowel. My question is: Can anyone point me in a direction to find inexpensive satin ribbons? I'd need at least 500 yards and doesn't need to be all one color. And is that the best type of ribbon to create that "ribbon dancer" effect? ribbon dancer video: https://www.youtube.com/watch?v=aptonWR8PLA
