You can't swing a dead cat without hitting a restaurant on the strip, or downtown.
Not a single dishwashing or bussing jobavailable?
This is the West, gotta habla espanol for entry level bussing and dishwashing. That or be pretty enough to be a waiter/ress, or have a degree (especially in Vegas) to be one of the chefs and cooks. Not because you need to speak the language for doing the job, but so you can properly take/handle the abuse and angst (sh@! rolls downhill) the more senior kitchen staff will dishout to you. He has better luck getting a job at fast food or chain restraunt as soon as he's old enough, equal opportunity employment and all.
I'd do chores or find an oddjob or two for some loose cash, save it up and then buy a prepaid credit card at the corner store to subscribe for AH. Not a lot of lawns to mow or snow to shovel in Vegas... oh, you know what you are almost too late for but could get the jump on right away, hanging holiday lights (and taking them down in early January) around your neighborhood. Start with all the old people in your neighborhood, do the work on the weekend when you and the customers are both home, then schedule an apointment with them in January to take them down and nicely pack them away in a box for them to store. Either price installation and the take-down seperatley or do some package deal.
