Jon, on a more personal note if I may.
I understand that your health has now prevented you from performing your regular work. My concern is that you might not have a clear understanding of just how hard florist work is. Also, owning your own shop is ten times harder. I would be concerned that this business might be the wrong thing for your health.
In this economy I wouldn't want you to invest what funds you have in a business that is itself having difficulty and would be almost impossible for a novice to get into, learn on your own and succeed. Frankly, Jon something your not aware of , is that there are well known shops closing everyday all over the US. So you might want to look at a job that is more stable, if that's possible where you are.
Best of luck to you, and above all please take care of your health. You have my prayers. God Bless.
