I have been setting up this photography site using a program called Koken.
I really like a lot of things about the program, including the fact that it synchronizes reasonably well with Lightroom. However I have learned that the current owners and creators of Koken wish to sell the company. This could be very good, or very bad, depending on who buys it, and what their vision is, and how well they implement that vision.
I think the most prudent strategy is to take a wait and see attitude, but keep an eye open for alternatives. Like I said, I do like the program, and it would be a major pain to redo everything, but I have been left behind by a couple of other web programs in the past.
