Here's a great thank-you gift idea for your clients; take some good "before" and "after" photos of your project, approximately 30-40 photos, and make a photo book for your clients. I've used both Shutterfly.com and Picaboo.com which offer many styles and sizes of photo books to design with. The average price for a 10" x 10" soft cover book is $40.00 including shipping. Which includes 20 pages. The hard cover books are priced a little more. This is definitely a special, personalized gift to offer your clients! They're sure to love it.
