Aculady makes a lot of good points. If you go the routes she suggests, though, I'd suggest hiring a professional special ed advocate. (Sometimes you can get one free from your state, but not quickly.)

I spent my DS's kindergarten year reading law to protect his rights, and it would have been much more effective for me to immediately hire out that piece of the job so I could focus on other things more closely. We ended up with a terrific advocate who was experienced in our district who negotiated a lot of help for DS, much better than I ever could have done alone.
