B.S. in chemistry from small local state school, want to go to grad school for Mechanical Engineering

[dallasfan12]

I am working on my B.S. in chemistry and I am wanting to go to graduate school for some field of engineering (probably mechanical or electrical). I have already completed a minor in physics and I plan on taking extra math classes to better prepare me. I am also taking a C++ class this fall. I have two more years remaining. My current GPA is about 3.4 but I hope to raise it to around 3.6. I have research experience at my school in inorganic chemistry and astrophysics and also experience at an industrial biofuels job. 

How do I go about finding schools that accept applicants for a Masters of Engineering or PhD that have different bachelor's degrees? I have had almost no luck so far. 

Thanks all
