Honestly, the Tech test shouldn't take you more than a few weeks of preparation. I used the Icom page at hamstudy.org and did the flash cards until my proficiency was up, then started taking practice tests. Once you can pass a few practice tests in a row, then schedule the real deal. Seriously. Do it.
I think it's possible to start today getting ready for the Tech-level test and be ready to test either Friday evening or Saturday afternoon at Green Country. I'd suggest upping the intensity to really learn the material comfortably. I recently passed the Extra test using Ham Test Online (http://www.hamradiolicenseexam.com/index.html) and they say a good student can be ready for the Tech in 10 hours. Their process adapts to your weak areas to ensure you understand concepts and the way they will be tested.
