Look online for homeschooling information for your county. Make sure you take him to the library, and field trips with him. Also make sure he has friends he can get together to play with at least a couple of times a week.
One word or caution, if you don't plan to continue the homeschooling please don't do it. After they get use to the one on one teaching, it's hard to put them back in public school. I homeschooled my daughter in the 8th and 9th grade, when I tried to put her back in public school in the 10th she was so far ahead of the other students she was bored in school.
