I don't really know any strictly tickle producers in SC. I know one or two in Columbia that shoot a bit of everything.
I'm kind of confused by your post are these women models or are they just normal vanilla women you know that you would like to see tickled? Do you know if they'd even remotely be interested in being in a clip? Also it sounds like what you're wanting is more along the lines of a custom, so would you also be willing to pay for said girls to be in a clip or are you expecting the producer to pay? Yeah having producers randomly contact random women to ask if they're willing to be in a clip is kind of creepy.
