You just need a bespoke Aviation course that is run by occupationally competent staff to help you get you into a good flying school.
On what basis have you reached that conclusion?
The vast majority of the thousands of people who have passed through the flying schools and gone on to become commercial pilots each year have done no such course. Such courses are certainly not specified as entry requirements for any FTO that I am aware of.
It is sounds like you have an personal interest in getting people to sign up for the Trafford Course.
