Rental flowers

We have chosen our flowers as an area to save in our budget. I would like to use a florist for all of our bouquets and maybe boutonnieres, but save when it comes to center pieces, ceremony arch flowers, etc. I have read some reviews about some rental sites (something borrowed blooms). I was wondering if anyone had any insight about the quality received, ease of use, etc. I’m also not creative at all so one of my biggest reservations is having the “eye” to choose flower arrangements that all mesh together with other decor too!
