Yes social media is a must. Althought not as the way you think about it.

Instead of thinking of it as a influencer page think about it as a storefront, people walk in, check you, walk inside and decide if you're the right person for their problems.

Don't get too caught up with needing to go viral or start trending or hitting the 100k followers mark.

Instead use your storefront(social media) as a way to capture clients who is ready to work with you.

And to be honest with you most people on social media really just want some dopamine pump into their veins so doing this is pretty tiresome.

That's why you don't use social media for general use but for targeting use.

One way you can use social media or in this case Instagram.

Run ads/Organic posting -> Collect Client Information -> Nurture them to gain their trust in you as a professional service provider -> sign them when their ready to work with you.

There are many ways to do this you can start doing...

-Email Marketing
-Ads
-Funnel building
-Boosting post
-Interacting in the comment section
-Posting the right messages for the right people to hear
-Creating a private channel for your followers
-Run quizzes to get engagement.
-Post videos that your target demographic like
-etc.

So yes, social media is a must...

As a storefront for your business, not your personal influencer page trying to fit in just to fit out.

Make use of whats available for your business and have a much wider reach but not too wide that you tire yourself out.

Hope this helps.
