i was a graphic design major when i could afford to go to school but it's been a while. i don't know how much programming i remember. i also worked for a printing shop and have done some freelance stuff in similar regards (web banners, logos, shirt designs, flyers, run the local little league site, etc)
i didn't look at the link as much as i wanted to as i was pressed for time, but i've bookmarked it to at least look at it
If you want to use that site, my advice is to know your strengths and leverage them. I probably don't push as hard in my proposals as I should, because even I know how to build a website in general, most people are looking for something they can maintain themselves, ie a CMS, ie Worldpress because that's the one they've heard of.
Wordpress in its most basic form is pretty easy, but of course I'm not making it easy on myself learning it the first time.
I'd probably have to do it a few more times before demanding money for it, haha. I'm such an Asian chick...
My other advice, which is probably more topical, is to leverage your network. I get paid $15/hr to do advertising layout for a wedding venue that my community college classmate referred me to. She was doing the job herself, but graduated and then got pregnant so she didn't have time anymore. I can't even command $10/hr on Elance.
And when I met her, I had no idea that she could make such a connection for me. It's very likely that someone you know might need design work (or whatever work it is), even if it's a friend of a friend.
It's a contract gig so it wouldn't pay the bills by itself, but the extra money (and experience) is nice.
