What type of jobs are good for me?

I like to design invitations, posters, and sometimes business cards (mostly invitations). I have programs on my computer like Gimp, Photoshop, and Picasa. I know many editing sites like Picnik and Fotoflexer.

I thought of a graphic desginer or graphic artist but I'm not good at drawing and I think that it's too open for me.

So, what jobs are good for me?

event planner or something in marketing
