its possible, my instructor at one of the mills in jacksonville flew 4 hours a day with me. I think he flew with another student too. But they all seemed burned out. Since you are in SE wi, there is one of these mills in Chicago, Dupage i think. Might want to consider it... Not sure if they have 141 programs though.
At the end of my CFII/MEI add on, they told me to apply for a job, but HR sent me an email within a week saying they were only picking from the pool of students who did the 90 day fast track. I dont know why exactly, but my guess is they gave priority to those who spend more $$$ at said puppy mill when a slow down in hiring happend. This was last jan/feb and the new ATP rule was 7 months away so most regional required 1000TT. Thats why i think they only offered it to those specific students.
