I was just married in June at Victoria House and I cannot say enough wonderful things about Kay Scott. She actually spends time with the bride and groom a day or two prior to the wedding. She uses this time to show you samples of her work, to take a look at the spot where you will be married and to discuss any of your want, likes, dislikes, etc. The day of our wedding, she showed up about 30 minutes ahead of time and was really helpful in helping me with my last minute preparations and decisions.
You're correct that she provides you with a roll of film (or in some cases, depending on time constraints, a sleeve of negatives) to take home with you for development. I had no problem finding a professional photographic and computer imaging lab in my neighborhood that was capable of getting the job done. The photos are absolutely amazing and I have no complaints about any part of the process - go for it!
