Josh,
Your thought process is by no means crazy! Thanks to the technology age, almost everything is online. I wasn't too sure myself what was out there. I did some basic research and this is what I found:
Taft Law School: http://www.taftu.edu/ If you look at their Tuition tab you'll see that it costs a little more than 7,000 dollars a year. That's definitely not a bad price! They are also accredited, which is important. Taft Law School is also a member of three different associations/groups. You can find it under their accreditation tab.
Concord Law School: http://www.concordlawschool.edu/ Concord Law School started it's online program in 1998. It recently also became part of Kaplan University. They boast that many of their students are graduates of the Ivy Leagues schools such as Harvard, Yale, and MIT. It runs about $9,250 per year plus fees.
There are more out there, but before I do more research I am curious as to what part of law you are interested in. Walden and Phoenix University pop up in search engines when you put in the generic term "law degree," but upon further inspection I can't seem anything except Criminal Justice degrees. With more information I might be able to find what you are looking for.
