can I get a job today or tommorow
depends on where you live... first, it's next to impossible trying to get a job this late in the summer (sorry) second, check your state laws... in the state of MD for instance, you have to be 14 to get a work permit unless it's a volunteer place. I'd recommend babysitting- I made $60 watching 2 kids play with each other and then fall asleep. that's an easy job. put yourself out there! (just be careful of what information you show people)
Not proper jobs, but you can help out people like washing cars or walking dogs or something like that, I remember I went car washing with friends to get enough money to go to a certain theme park And we made 40quid in one day!
probably not today or tomorrow. depends what you want to do and if theres space(:
