Depending on where you live, some school districts have homeschool divisions that you can educate your son through them. You have their guidance and expertise and yet they are still part of the school district. They would help you make sure he graduates with a District diploma.

Also, school districts may also have on-line programs that they can do at home. There are also separate on-line programs such as K-12.

I would look into those to start if you do not feel comfortable doing it on your own at first.
