Again, if your website isn't ready to send folks to, social media marketing should be the last of your worries.
Having a social media presence is great, yes. But if you need to hold off for a bit to get your site in order then bring someone on, by all means!
To be clear, I'm not saying because you don't have a website to not do anything. I just think it's important to have a website, landing page, email capture. Something to send ppl to.
LASTLY, I am also not saying you cant utilize social media first.... but don't be sending ppl to your site and it's halfway done... k I'm done
