To drill through concrete you need either an impact drill or diamond bits, which are cheep on ebay or 5 buckaroos at harbor freight. It's better to cast around a big hole in place, but you can still get cheep core bits which are huge online. Use water to keep the dust down.
The curse of not finishing projects doesn't last forever, I started being realistic with what I can actually do and haven't failed a project in 3 years, it gets easier.
oh nice pic too
