In need of JUMBO sunflowers, jumbo arrangement. Fayetteville, AR

I am a Director of Sales at a well known global hotel brand. We are having a ribbon cutting next Tuesday morning.

I had a city event 2 weeks ago where my farmer friend who is for the most part retired, provided a jumbo arrangement of jumbo sunflowers. Ownership wants the same bouquet but my friend is in the hospital and won’t be able to do it. If I am in the wrong sub, I would love redirection. Thanks!
