Well, there is always someone that will be willing to do it cheaper but at what cost? It all depends how well you want to preserve the memories of your BIG day that to be cherished for the rest of your life & generations to come. Think about wedding photography in this context. How will you remember the beautiful sparkling decor, the amazing dress you wore for that one day & that expression on groom's face when he saw his bride coming. Does the photography do it justice? The only thing that will stay with you to show your children and grandchildren are the photographs, so this is the last place to make a compromise :) .
