Looking for floral designer willing to work with...

My family is curently in the flower business and has access to plants/flower/cutflowers at wholesale prices. We are not a florist, and although family members are more than capable of creating beautiful pieces, this is not their area of business.

I am looking for someone who would be willing to work with me on the design and labor aspect of each piece for my wedding but I'm also looking for someone who will allow us to go through our wholesaler for the flowers. Again, my family has a wholesaler they work with and it would kill them to spend retail price on flowers they are able to get at wholesale.
