They have some very good online lessons at
www.workshoplive.com
You can subscribe to the site for around 19 bucks a month. That's a heckuva lot cheaper than what a live teacher will cost ya. They have some awesome teachers over there!!!
Also, get a drum machine of some sort, and start jamming with drum patterns and loops. I have a Zoom HD8 multitrack that has a built in drum machine(500 patterns)....so that is what I use. If you are on a budget, get one of those cheap casio or Yamaha keyboards that has built in drum patterns. That'll work.
You might also want to go to a local music store and pick up a few of those book/CD combos on bass.
Play along with your favorite tunes on your iPod or whatever.
Get as much as you can free from youtube, and online etc.
Jam with other musicians...as soon as possible, and as often as possible.
If you have the desire, you will find a way.
Get busy. Be focused and dedicated.
Listen to a lot of music and pay attention to the bass lines.
