There are lots of homeschool groups out there. You may need to do some searching online for one.
These groups have people who have been through what you have and know the ins and outs of the local school districts they have worked with or around. They will be able to tell you the best curriculum to use that will match your school district's (because if you decide not to continue, your daughter will need to go back and have the credit necessary to do so).
Some also have classes available for homeschooled students. I believe one in this area is H.E.R.O.
Once you know what curriculum you are looking for, you may find it on craigslist or Half Priced Books.
And, as a former classroom teacher, I highly suggest sitting down with your daughter and making a DETAILED plan and routine and sticking to it. You may also want to download the state's standards to follow and use to write your plans. It may be the proof needed to re-enter the school district.
Hope this helps!
