What should I do for my first job?

I'm 18 years old, and i'm looking for a first job. I'm into computers and the IT field, but I don't have a college degree or any experience to help me out in this field. I'm kind of a shy person, not really into talking to alot of people or something like that. I'm wondering what kind of opportunities are out there for me. I'm hoping to make somewhere between 8-15$. I know i'm probably not going to find anything in the IT field, but i'm just curious what I could do. I live in frankfort, Kentucky right now, but i'm moving to Independence, Missouri in a few weeks where i'll be living with my girlfriends mom, and i'll have to pay rent and car insurance etc. I just need to find a job, any ideas?
