Aurora, the most impt thing is the budget.
As now, u dun hv much time, ur brother might hv to fork out extra coz everything could be done in a rush.
For PS, you could go to those photography studio and take a portrait one if u dun need any album coz i think it will cost only a $300-$500 bah.
But like iVied says, its pretty common that alot of couples are doing away with photo shoot!
