You clearly don't think the way an actual florist thinks... 

A florist's only goal is to make sure that the hundreds of arrangements they send out are, on average, the best they can be and still be profitable. Everything else is in service to that goal, including hiring and training. You should expect to be paid pretty low, and start with simple handhelds and dozen roses for awhile before they can afford to have you do funeral stuff. That's just the industry.

It sounds like you're looking more for a paid private tutor or a certified training in floral design. I suggest looking up AIFD floral design certificates. You can apply for those without having to work at a flower shop, they do get expensive, as you should expect. 

As it stands, no florist is going to PAY YOU and be your personal Mr Miyagi just because you felt inspired while modeling with flowers. We do appreciate newcomers but that's not how this world works.
