Vendor Help - thanks

I am interested in a few vendors- can anyone tell me if they have used any of these and if they are expensive?

Velvet Studios- I know this is a LIW favorite- but are they expensive?

Stefan's Florist- I am getting married at the royalton & a condition of booking there is that you have to select one of their two florists.
