Good luck on the LSAT. I suggest taking a commercial course and learning the strategies to master it. However, as a recent admission to the bar let me paint you a really clear picture of the other side of the fence.
First, the job market his horrible for lawyers right now. If you are not in a top tier school, it will be very difficult for you to find a job. I went to a tier 2 schools, and MANY of my fellow classmates still have yet to find a legal job. Most are living at home, or working crappy minimum wage type jobs.
Second, if you are doing it for financial reasons, somebody has misled you. I make less money as an attorney now, than I did before law school. More importantly, I was debt free. Most lawyers I know do not drive new cars, and don't have thousand dollar watches on their wrists. Go talk with lawyers in that field. Get a good feel on what exactly it is they do, and make sure it is something you want to do. Look at what they drive and what they wear, as you will have similar income levels with your peers.
Third, it will be close to impossible to get into the certain type of law you want to be in right off the bat. There just are not that many openings at boutique firms unless you have a serious connection, or share a similar IQ score with Richard Epstein.
When I was applying for law school I thought I wanted to be a business lawyer, and never step foot in a courtroom. I even had an MBA. I takes with people in the field, and realized I didn't want to be at a desk writing memos for the rest of my life. I am now a trial attorney, and make less money now than before going to law school, and I could not be happier with my decision.
Good luck OP
