Florist Prices

A friend of my FH offered to do our flowers. He is a professional and is supposed to do great work. (Obviously I would look at it before booking him!)
Just wondering how much you guys are paying for your flowers..esp. CPs and how much for everything else? We are having a very small wedding party so we don't need a lot of bo-ks
just trying to get an idea of what the average is so we can decide if we need to meet with a lot of other florists...he's quoted us on CPs already but not the rest and I have no idea what is the norm for any of this!..feel free to FM me if you want..thanks!
