I mean, there have been a few providers like
@Lunaseraphim who mentionned being interested. I think it would likely be necessary to be organised and probably have some form of deposit up front, as it sounds like the kind of event that would be too easy for people to flake out of.
I can think of at least two providers that certainly might be interested, if only just because they seem to really like cim, and/or glory hole type events.
I know that AmberMTL who seems to be back at work in Laval for the easter weekend would likely be a very good candidate. Maybe organising that with her and a second one would be a very interesting proposition.
