I have one, but it doesn’t seem to be too popular. You seem to be of the mentality that if you don’t get a job in your chosen field you just won’t get a job.
Suck it up and get a job in a fast food place, department store, restaraunt, or some other “menial” job. If you get one that doesn’t work you 9:00 to 5:00 Monday through Friday you’ll have a weekday or two off per week, which will give you plenty of time to set up interviews, plus the bus fare to get to the job (you may have to borrow money to get started out, if public transportation is your only option).
Even if they work you Monday through Friday (or even seven days a week) from morning to afternoon you can still set up interviews. When my brother wanted to change companies (same field, he was just upset with the company he worked for) he would work until late afternoon, then go on interviews.
The bottom line is, if you think any job is “beneath” you then you won’t make it. The burger flipper is just as necessary as the graphics artist. The construction worker is just as necessary (maybe even more so) as the web site designer.
Just suck it up, go to McDonald’s, Hardees, Arby’s, Burger King/Hungry Jack’s, Wal-Mart, Target, and any other place that might be hiring and look for a better job in your downtime.
