STEP booking is similar to FHR booking under Amex Platinum/Centurion Charge travel benefits but you can booked through any STEP accredited travel agent. I searched the internet for such an agent last year and eventually picked one located in Canada (because of the quality travelmadvices shares on its website site) - Prince Collection. Great service and everything was clearly explained and I even troubled them with a cancel and rebook for a better deal! Payment was to be made at the hotel so minimum financial risk. As a matter of fact, the booking showed up on my ALL account almost the same time as the TA confirmed booking had been done.
