Strictly ME?
If you are strictly looking for the ME, MEI, I would go to one of the schools that does it flat rate. I did that, it's intense, it's thorough, and you walk out knowing how little you really know.
Once you have the ME/MEI, it's easier to rent. Doing it the old fashioned way, show up today, a few days from now, etc, will drag the process out, and you'll forget more than you remember.
