Modding Xbox 360

I been looking into Modding my xbox 360 but the thing is the only thing I have ever modded was my Nintendo Wii. And that was soft modding. Nintendo Wii was a snap but I am over whelmed when I started looking at info on how to mod my 360. Only reason I want to mod my 360 is to play emulators on the system vs on PC. My question is that is there anyone that has successfully Jtag there xbox 360 and can help me with my own. Either by posting steps on how to do this an easy way or I can pay someone to do this for me. I prefer if someone can do this for me and I can pay them. But I am not helpless either.
My Xbox 360 is a Falcon xbox360 v1 2007 or v2 2008 Philips lite-on DG-16D2s :curses:
Any help is welcomed
