Portal380, if you are looking in California, I would recommend you stopping by Angel City Flyers in Long Beach. They are a well set up school and use G1000 equipped DA40 & DA42s. I did my PPL with them & have just started my IR.
I did my PPL in 23 days (18 actual flying days), so they can work around your schedule if you are prepared & willingly to work hard. That was hard work. Doing an IR in 10days would be tough IMHO
Worth a look if you are over. Give Seosamh (prounonced Joesph, just replace the J with an S) a call. Helpful & friendly guy.
Let me know if you need anymore info.
