Hi Miho,
I too am not having the photoshoot as my HTB is not in Singapore. However, there are BS who offer a package without the photoshoot.
By taking up the BS package, your WG, WG, kua, hubby's suits, flowers, make-up, car etc..
So in short, it's like a one-stop thing. In fact, you can speak to the BS and ask if they have calla lilly bouquets. My understanding is that unless the flowers are seasonal flowers, they can accede to your requests.
If need to, I can recommend you my BS. I am with The Aisle, and basically everything including AD PG and VG are from them, and the bill comes up to about $4k.
