website for my band

I have an online course that I am selling for jazz musicians with a webinar, I am looking for anyone who can help get quality traffic of jazz musicians for my online course in any way or form, perhaps by posting on Facebook groups, that will get people to sign up for the live webinar. Important note I do not want to operate from my account or with my picture because I don't want to get blocked on Facebook, but I saw that posting on 100s or even 1000s groups of musicians on Facebook (specifically in the usa) generates good traffic for my webinar, which turns into sales

also if your an expert in facebook ads for musicians or google ads for musicians and you think you can help in that somehow you can approach as well.
