Where do you buy transmission parts?

So if I have Shindley do it for me. Can I just pay him the money, so he can get the parts. Because I have no clue what parts I'm going to need. My car will mostly be a daily driver...since its my only car. I want to make some power, but not ALOT...yet. I just want to be able to get into the low 13's and I'm fine for a little while. How can I contact Shindley? I'm hoping on being able to rebuild before the first Rock Falls...if all goes well.
