Regarding bringing balloon for photoshoot, I did that! But need to take note that helium balloons can only last for 8hours, and the lifespan is even shorter if its under hot sun, outdoor environment. So you cannot pre-buy the balloons the day before, else the helium will be gone and the balloons will not float. What I did is to order the balloons with the shop and paid $16 for the delivery. So that morning they will pump the balloons with helium and deliver to the BS where I'll be doing my makeup and changing to photoshoot gown. =)
