What to do when you're out of options applying for serving jobs?

Ok, so I just recently started college classes at my university and I had to cut my hours at my full time day job to a mere 5 hours per week, with an occasional Saturday morning (three between now and December). This will only bring me about $200 a month in income. My bills add up to $725 a month, so it’s obvious that I have a bit of an issue.

I knew this ahead of time and started applying to night/weekend jobs about a week and a half ago. I’ve had NO luck. I go in between 2 and 4, but there’s never a manager available to speak to me. I call before I go in so I’m not wasting my time applying somewhere that’s not hiring, and most of them tell me that they just got done hiring a bunch of people and have a full staff or they’re only hiring hosts, which won’t give me enough money.

In case you haven’t caught on, I’m applying at restaurants for serving positions because I figure it’ll bring in the most money with the most flexible schedule. I’m in school Monday through Friday from morning until 3:30PM, so now that my classes started, going to restaurants between 2 and 4 is nearly impossible. I have serving experience, but it’s been since high school (3 years) since I’ve done it. Since then, I’ve had more “professional” or office jobs. Two of them, in fact.

I’m filling out the applications to the best of my ability, putting down good references, and calling every couple of days to check on the status of my app. Still, nothing. Not even one interview. I guess with school starting, all the students already got the jobs I’m looking for.

So, I am going to hit one or two restaurants a day after class for the next week or so, but I’m thinking about going out tomorrow and hitting about 3 or 4 that have confirmed they’re looking for servers. I know it’s not M-F 2–4, but do you think I’ll still have a chance? I mean, what else can I do if I’m in class when they want people to come apply?

I know finding a job now takes time and I’m just being a big whiner, but I guess I figured finding a job that pays $5 less than minimum wage wouldn’t be so frustrating. I feel like I’m doing all I can at this point, but time is just running thin here.

Thoughts?
