I loved Root Photography as well, and they are definitely more expensive, I believe their packages start at $5000, but I would ask and they may be flexible, not worst they can say is no. An alternative is Studio 222, they have a similar style to Roots and are up and coming and cheaper. Princessshea used them on here and I love her pictures and she convinced me to use them.
Although I can not give you a full report as my wedding isn't until January, thus far they have been great to work with and were flexible with what I wanted since I am flying them to Puerto Rico for my wedding and DFi and I are doing a honeymoon shoot at Disney with them the next week. Becka is a sweetheart. You do have to fill out a contact form on their website to get up to date prices, but they are quick to respond and it gives you another option if the Roots are not in your budget.
