The freelance consultancy work was paid at around 500 pounds / day for TRE / TRI on the 737 in approx 2000 . I did it for approx 3 years off / on and then gradually gave it up on the grounds of interfering with the day job / inconvenient geographically / not worth it . The other factor ( sorry , folks ) was the ' new wave ' of TRI / E's who apparently would sell their time for the lowest undercut price on a ' pick me ' basis that the training providers lapped up . Disappointingly in contrast to the natural laws of inflationary economics the price for instructor time appears to have gone down or at least remained static. While I would not wish to endorse melodrama and state that this is a factor in declining standards within the pilot training industry it certainly doesn't help.
