What concerns me is that you do have reservations about it and that for the next 9 months you will be constantly worrying about it. You'll have so many other things to get on with that you don't really want something like that on your brain every day. It's just not worth it. If you can overcome the issues and have confidence that everything will be fine, you can just forget about it for a while.

In some ways it is a challenge that you should readily accept. After all, it's not an impossible task, the flowers should be available, they should keep for a week at that time of year if you look after them. Other florists do it. If you can sort it out you will feel so much better about taking other things on. It's all a question of whether you feel it's just too much hassle for you.
