Under consideration is
Lilly-Coco collective
Kylie-PDC (seen her twice before 😍)
Rebecca-Dim Sum
Have you met Janet West? I'm not sure if she would meet your definition of "curvy" but her rate is 600/hour now and she is great.
Cereza Caress could be another option. She is a bit bigger like Kylie-PDC but also great and a fairly low rate.
Karina Espinosa would probably be perfect but she only visits Vancouver occasionally nowadays. I just noticed that it looks like she will be visiting Vancouver the last week of July so you may be able to catch her then. However, I also noticed that it looks like she may have a minimum appointment length of 90 minutes for $700.
Sovanna Kim could be an option too if you like enhanced tits.
