I am a senior citizen (for lack of a better term) relocating from WA State to LC in March of next year. I would like to know if anyone is aware of any reputable technical or business schools in LC that specifically teach desktop publishing/graphic design? (as opposed to a 2-year or 4-year college such as NMSU.) I have some pretty fair skills at this but want to hone them a bit. Apart from my full-time social services job, I have a small startup business on the side doing design and desktop publishing for friends, family and a few others as time allows.
I would like to get some kind of certification but don't want to devote more than two years max to school. I'll be working two jobs so won't have much time. Taking Internet courses is an option but not the ideal for me. I like hands on teaching. Any suggestions or ideas?

Any information you can offer would be appreciated!
