Starting my Wordpress Maintenance business! Need advice

Hello,

Hope you're all doing good. I've been doing Wordpress for 10+ years now. Mostly I've been jumping on freelancing platforms and it's been okay, I can't complain but I really need to go to next level now, I am starting my WP maintenance service to have a bit more control over my business.

I've checked my competition and I've no doubt I can provide better bang for bucks but that's not the tough part, as all of you know, marketing is scary (atleast to me) so I need some advice there.

I have already planned on trying to market it via Twitter, joining communities, FB Group and some video marketing. What would you guys suggest? Any help would be immensely appreciated

Thanks!
