Going to be tough, especially coming from a small school. How good is their physics program? Do you have a course catalog online or something that lists the available classes?
You might have to go to graduate school to get a Master's in whatever engineering field you want before you can become an engineer.
The reason I say this is because employers won't really want to hire you if all you know is physics from a small school. But a graduate school won't be as reluctant to take you on. You will however have to make up for it a bit with undergrad classes at the new school.
