Children's book photos

I am completing a draft of a children's book titled "Busy Little Feet" I am needing some color digital photos to complete it. The pictures will be for a fun five page section and will show a younger child (5-7yrs old) who has just had their shoes and socks taken off and being playfully tickled on their feet by an older child ( in the 8-12yr old range) showing the younger child giggling really good. A variety of expressions and reactions for these pictures would be great. Then showing an older child or parent come in and start tickling the older child's feet while the older child tries hard not to laugh at first--still tickling the younger child then busting up and start giggling showing the older child really giggling hard--then a few shots of the older child being tickled on their feet by the older child or parent and the younger child at the same time with the older child going nuts giggling. So the pictures will tell a fun little "mini story". As long as the pictures look fun and playful--that is the mood I'm trying to capture. The pictures can be taken indoors in a living or playroom--again as long as they look playful and fun. I plan on using several differant pictures for each page and putting the pictures in montages on each of the pages. So taking alot of photos will be important. I need the pictures in color and digital if possible in jpeg format. The pictures can be e-mailed, uploaded to a site for download or burned to a CD and mailed to me. I would like to see a few samples of your work and a sample picture of the kids you plan to use for the pictures.
