My first instinct is to avoid big schools. Tuition there is steep, not as steep as places like ERAU, but still pretty hefty. Have you checked out your local flight schools? Going through an FBO or local instructor can be considerably cheaper.

PPL - 40 hours = ~$6,000
IR - 40 hours (80 TT) = ~$6,000
CPL/SE - 170 hours (250 TT) = ~$17,000
CPL/ME add-on - 5 to 10 hours (255-260 TT) = ~$1,250-2,500
CFI/II/MEI - 10 - 15 hours (265-275 TT) = ~$2,250
Miscellaneous costs (books, checkrides, etc.) = ~$1,000
Total cost through an FBO or local instructor = ~$34,750.

And if you're real clever, you'll start training for your CPL/ME add-on and CFI/II/MEI while you're building time towards 250 hours. You'll save some good money doing that. Word to the wise, get your written exams done ASAP. Do 'em before you even start flying, get them out of the way. When you do though, be sure to take all the exams that come out of one book (e.g. studying for Instrument Rating, take the Instrument Rating written as well as the Instrument Instructor written).

Man, I wish I was still in the instructing business.
