Thanks for the advice. That was my original plan, but I've since changed my mind. I know exactly what has to be done, and the reasoning behind it (and trust me, I've LOVED learning everything about it!), but for the sake of time, and ensuring the job is done right, I want to have it done professionally.
The rest of the install I have done/will be doing myself. You're right, it is definitely satisfying to know I've taught myself (through the help of everyone here on the forums) some pretty difficult things, and have the end products to show for it. Hell, I even sucessfully made this:

I've been dragging my feet on this install for quite some time now because of this issue, so I want to get past it so I can finish everything and enjoy my Mac on the go!
