Hydrangea's in bloom?

Hi neighbours!
I am making floral centrepieces for friend's garden wedding this weekend, and wonder if anyone is willing to part with a few white or greenish hydrangea blooms from their garden? They are looking gorgeous around the neighbourhood these days, and if one or two people wouldn't mind giving up 6 or 8 blooms - it would be greatly appreciated! I'll even exchange this for some weeding in your garden :)
