Isn't there a thread on 10 day instrument rating courses in here already?
Get your instrument rating in 10 days? SURE.
Be capable of flying IMC single pilot in 10 days? GOD NO.
If there is one rating that you shouldn't try and cut corners with this is the one. If you're looking for a career you need to build time for your commercial anyway so use that time to become an experienced and competent instrument pilot.
