Looking to pay cash for lead generation - music production subscription service

Hi guys, long time lurker but first time poster. I have set up a monthly subscription service aimed at music producers. I am currently running FB ads and doing cold emails, and my website conversion rates are good. Now I'm looking to expand as rapidly as possible. I'm looking for people who can drive traffic from reddit, twitter, instagram, quora, etc. Any method aside from FB ads and cold emails. The monthly subscription price is $9, and I'm offering a commission of $5 per user that signs up and stays at least one month (since there's a 1 month free trial, this means that I have received at least one payment from the subscriber).

Could be quite easy money for you, and I'm open to the use of bh techniques as well.

Thanks for your time!
