I.C.
There are plenty of resources out there for homeschooling. Joining homeschooling associations is a place to start. They exist and are on the web.
http://www.home-school.com/groups/IL.html Here's one for you to start with.
I have never homeschooled, but have had a close friend home school her children for 10 years. She sent them to school after that, and they were completely on target for their age group and grade level.
If this decision is made, make sure that you are prepared with the right curriculum that if the opportunity presents itself and your kids eventually return to school, you know that they will be ready academically.

In order for you to homeschool, you must read all that you can on the process. In MY opinion, you should be at least college educated. You should be able to not only teach all subjects and curriculum that your local school district teaches, but I also believe that you should also be fluent in every subject you teach. My friend that I spoke of is a double master's degree and is an educator herself.
J., please do not take anything that I say as a way of trying to sway you in any certain direction, but I think you should seriously reevaluate your decision. (Gina, don't try to correct someone else's spelling mistake and make the mistake yourself with the same word)
I just want you to know all the facts. You may have made the decision and your feelings are strong, but you really need to consider the future. You don't know if 5 or 6 or 10 years down the road you will, for whatever reason, need to send them to school. It would be a complete injustice if they are sent to school and are not prepared for the world of public education.
I told you about my friend that succeeded in homeschooling, I also know of another child that was homeschooled by her 20 year old half-brother while the parents worked. This school year they sent the girl to school (3rd grade) and she ended of being in my son's class. I have seen her work. This past summer, she was playing with my kids out in the front of the house and they were playing "school" and what I saw was SCARY! This 8 year girl cannot read and has the handwriting of a 3 year old.
Now, I'm not saying that you're going to slack. I'm just giving you my experiences and observations. Homeschooling is an incredible commitment. Just make sure you're ready for it. Starting with making sure that you correct your mistakes; spelling, capitalization, and punctuation when you are writing.(I noticed this from your post) Children watch us and mimic everything we do. If you become their educator, you must be on top of everything at every moment and never letting down your guard.

One last thing, know for sure by having evaluations done that none of your children require special services that you will not be able to provide by homeschooling. Homeschooling a special needs child adds to the already stringent commitment. I know that you previously posted about one of your child's speech delay. This issue must be addressed.
This is another reason that my children go to school. My son requires special services which I cannot provide at home.
Good luck with your decision.
