Math major, no accounting classes/exp, want to get MAcc.

I graduated Dec '12 with a 3.8 GPA in Mathematics from a low-ranking state school. I have no accounting courses or accounting work experience. Lackluster work experience in general: about 7 years of part-time retail before/during/after undergrad, and 2 years in a factory doing manual labor. I gave dental school a try but it wasn't me and I dropped out at the end of the first semester.

Given my academic backgrounds, any suggestions on which schools I should be looking at for an MAcc? I want to work with the Big 4 out of school -- not for life, but just to build my resume and lay a foundation for the rest of my professional career -- so a school with good Big 4 recruitment is important. A program with affordable tuition would be nice, too.

edit: I haven't taken the GMAT yet.
