Apart from a national disaster requiring congressional intervention there are no exemptions and no exceptions to the 45/180 day periods.And furthermore your Qi is not even trying to be a smart fraud because the 45 day identification is irrelevant at this point.  

I have started sending out brochures about my company with testimonials from my previous sellers.

Even their online testimonials were nothing but "creative".  

I think this is a process where u never stop learning as you read testimonials of so many experts that have succeeded in this business.

Proof could be a statement signed by him, a video of his statement (video will), or the testimony of persons.

The person giving testimony must have seen/heard the act themselves, in-person.

Congressional leaders released a long-awaited framework Thursday for President Joe Biden’s signature Build Back Better plan, proposing a top-line price tag  of $1.75 trillion which includes investments in affordable housing and down-payment assistance and spares real estate investment from the most feared taxes.

Can you provide me with references or testimonials from previous home buyers? 

Any podcasts of testimonies of the ones that have done it?  

Verbal testimony is very common in court, so of course this is useful.
