Just $225/hr? Are there any hidden costs?

Apart from 6% Idaho sales tax (not included in the $225/hr) and any travel costs for out of town weddings, nope! That's it!
How many hours should I book?

This is a hard one and varies from wedding to wedding. It depends on which sections of your day you want covered by a professional photographer. Some couples want coverage of the entire day, from the bride and her girls getting ready to the happy couple's final getaway; others are content with a few posed portraits and coverage of just the ceremony and reception. Generally I recommend allowing one hour for posed photos of the bridal party and family, and another hour for posed photos of just the bride and groom. These photos may take less time, but it's important for you not to feel rushed so you're comfortable, and for me not to feel rushed so I can set up properly and take the best photos possible!
Work backward from the start time of your ceremony/reception and figure out how much time you'll need to prepare, whether the bride and groom want to see each other before the ceremony (important for figuring out whether to do posed portraits before or after the ceremony), and what are the key moments you want captured. Give yourselves margin! It can also be helpful to create a shot list of your must-have photos, particularly when it comes to groupings of family members (i.e. bride/groom with both sets of parents, bride/groom with grandparents, bride with just her siblings, etc.).
How do I pay you? Do you require a deposit?

I accept check, cash, or PayPal (3% processing fee applies), and require a 50% deposit of the estimated total in advance or on the day of the wedding. If I end up working more or less time than expected, I'll adjust the remaining total accordingly, which is due only after you've received your photos.
Can I see a sample entire album of a wedding you've photographed?

I don't post entire wedding albums online merely because these albums often run from 400-1000 photos, but you can view highlight albums
on Facebook or
on the blog which each include 100-300 photos!
