Look first at your local courthouse. Volunteering at the State's Attorney's Office is a great start. Look to see if they have any paid positions available also.
Look at local law firms to see if they are hiring, even if just for temp work or clerical.
**Yes, you must have a specific degree to be a paralegal. But, you don't have to be a paralegal to work in a law firm or similar area.
*** Duties include assisting the attorney with drafting documents and organizing files etc. Basically, you are there to make sure the attorney can do his or her job and do it well. You will do research/investigations for the attorney as well, more or less depending on the firm and their needs. I think what is more important is what the paralegal CAN'T do - ie practice law, set fees,etc.
Depending on the firm, your hours and ability to work from home will vary. It completely depends on what that firm or office is looking for. I wouldn't want my paralegal at home, as I would want to have face to face convos with her regularly.
* also, be aware that as a paralegal, you won't see much if any of that court action you enjoyed and the reason for your push. So, keep that in mind. It will most likely be a "regular" desk job behind a computer most days. But, you could get lucky and work for an attorney who spends tons of time in court and brings you along for the ride!
* Cash_Twins stereotype is unbelievable. Some of the best people I have ever met are attorneys. Some of the most vindictive and shady are pastors. People hate lawyers until they need them, kind of like the government. Generally, laypeople have no idea what it take to practice law, yet they want to talk about how incompetent lawyers are. Find a job that pays well and you enjoy. You can't go wrong.
