Some TMS clinics are offering the SAINT protocol off-label. Not covered by insurance of course, supposedly runs around $6k.
Unfortunately for SAINT it looks like you also need fMRI to correctly target the therapy...that's going to be a bit tougher to DIY.
You can also search this TMS FB group https://www.facebook.com/groups/285541688306686 for "saint" and find other people's experiences.
Edit: Apparently, the clinics that claim to be offering it might just be doing something that is loosely based on what is publicly known about the SAINT protocol. Dr. Nolan Williams hasn't released full details, so it's not possible for clinics to replicate it exactly. This clinic https://www.cambridgebiotherapies.com/accelerated-tms/ talks about how they've tried to reverse engineer the protocol at the bottom.
