As big as I am on DIY - I didn't mess with the electrical......much....I had a commercial electrician friend come and perform the install (and was teaching me as we both went along together). Maybe I'm paranoid, but when it comes to safety, I didn't want to run the risk of not wiring proper or to code. I was fortunate to find a great guy that was interested in teaching, and I'm at least more comfortable now doing basic electrical - but I still hire him back to validate my work just to be sure!
I leave anything in the way of big electrical, plumbing, HVAC and gas to the pros, and consider it money well spent for peace of mind. I do however follow them around to soak up as much knowledge as they are willing to pass along to me, so at least I can understand the basics of what's in my walls and be able to deal with minor repairs or installs
If you can befriend a licensed pro that is willing to help pass on knowledge, I would encourage you to take on some of the work with their guidance - then you have the joy of learning new skills coupled with the safety net of a professional's eye and experience!
Cheers,
