Many if not all SPA's want a CBC, they are less worrisome in general, bring a unique level of "warm comfy feel" and a level of confidence in English to the SPA for specific customers that are knowledgeable about the in's and out's of the AMP labour market. Everyday you can see in the SPA thread posts CBC's. You really should try look them over typically they are all posted by 11 am advising the roster. Places like QQ (Misha), VIP (Vicky) and more have them, I am not interested in that "Canadian" aspect so much, I am not even paying attention, but I see a good number.
Only you know which area, price etc. you want so my advice is to search the morning SPA Thread Posts, if you can't find anyone specific that day but you can see a few SPA's in your area of interest, then shoot a message to the Promoter asking them, "Hey, whats up with the lack of talent, you bastard?" "FFS, can you guys put your paper straws down long enough to help me find some quality CBC?" And just note, they really like when you ask them "respond, and be quick about it."
Just joking, there's no Promoter named Bastard, and they do try to distance themselves with being overly "quick," except unavoidably in the SPA room.
Most of the Promoters are not only extremely helpful, they are often the most knowledgeable about where to look. They may not have time to read all these posts and so that's why I suggested to find something "in your area / price / and service level too (Legit, Semi-legit, Holistic) and shoot them a message. Good Luck.
