its easy, the hard part is to promote IPTV a difficult topic to promote via social media.
another issue is if you service is poor you will have to handle your customer request and issues and that take time and is not worth your time
10 years a go was great, now i honestly handle my clients and those ones that they refer me, my supplier is great a few issues a year, and i keep the service because i used it because save me some money by no paying Netflix and the rest of platforms and the movies and series are available right after the premiere
