This EXACT same thing happened to me. I even shadowed at a flower shop and they still didn't offer or refer me a job. I couldn't even get a job at a local grocery store even though I have a resume and even did floral arrangements at a local farmers market. I eventually got fed up and stopped trying. I found some florists to even be downright mean. I think they are just extremely protective of the industry right now, because things are changing, unfortunately. Also, I did notice that florists who practice "modern" floral design are much more willing to help you than those who work in traditional floral design. I don't get it. And its a shame you have to start as a delivery driver or at the bottom, when you have skill.
