I think most two-year colleges are familiar with home schooling and won't require SATs to get in. They cost a whole lot less money, too, and usually have scholarships available. Transfering as a junior, it'll be easier to get in to a four-year university since there are usually lots of freshman applying and not so many juniors. My daughter did this successfully as did one of her friends.
Best of luck success! (don't know if you're ready for luck, yet.. ) Emma
