Just checked out GA Ready and although it's good to see someone running this type of training, this is the stuff we taught at the flying school I worked at in the early 90's. We had a C182, C206 and a C210 and we would endorse CPL holders on them and give them 5-10 hours on them before they went north (Northwest) looking for their first jobs.
This is what the flying schools should focus on, rather than CPL pilots who have only flown Diamonds (and the like) and thing they will be an airline pilot after they finish their $90-100k course.
