It's different in every state, so I don't know what your options are for a community college and if they require SAT/ACT testing. Back in Virginia, I don't thinking they do, but you're required to take a placement test and if you don't score well enough, you need to take remedial classes. Given all that, they are required to accept everyone.
As for a job, that is a problem, being in such a rural area. I'm not sure what you can and can't do, but if you need a job in order to afford to take the SAT or ACT, then maybe check in with the closest unemployment office? They should have counselors there that can help you with getting a job and figuring out what you can and can't do.
