Mr Simkins retired a few years ago
The trial would involve people using IBT at home and monitoring their own progress with regular check ups that would coincide with routine appointments.
A good point about the quality of mattresses, something that would require some consideration, and possibly a trial eligibility criteria that would involve the person considering the trial to replace a poor quality mattress.
Regarding spending money on advertising, this is something I could not afford. Though have achieved a reasonable amount of free publicity in papers, magazines and television. The problem here is still feedback. Involving the medical profession would improve this problem.
The website is already in place with a forum for this purpose, though poorly attended. http://inclinedbedtherapy.com
I believe we already have a huge amount of information and reports from people, including before and after photographs of chronic venous insufficiency (varicose veins) improvements.
As for banging my head against a wall, one gets used to it over 17 years.
So why not set up a trial yourself with Mr Simkins? It seems you're very motivated to do so.
How would a trial work, would be done in a hospital under controlled conditions? Would it be done in patients homes with set size blocks under the head of each bed?
How does the age and type of mattress in each persons bed effect the sleep each person receives?
I'm not sure of the benefit of spending money on a trial, personally I feel you'd get a better result spending the same money on advertising the idea and getting people to try it.

Set up a website with a series of set questions to get feedback and there's your trial.
If it proves positive you're now armed with a huge amount of information to push for a fully controlled funded trial, without that you're going to be banging your head against the wall and not get anywhere.
