How to equalize your time as a solo founder?

This is a question, not a 'know how'. Just launched my website/mvp of my startup, doss, a platform for photographers, videographers, and all content creators to setup a clean and simple storefront to upload their art as a product to sell to their clients and fans in an easy transaction without the need of a headache to create a website. After launching my mvp, and I know it's still new as I just launched last week, how does one setup their time with marketing, buildup of the website, review of new user products, and others? Is there a way when things start picking up to equalize ones time? Would love to hear from other solo entrepreneurs. I'm heavily marketing right now, mainly social media (instagram) but will move towards youtubers, bloggers, tech/photography/film/ magazines, and podcasters. And while doing this completely bootstrapped. My link is https://doss.mycnmi.com if you want to see my mvp. But mainly interested in the conversation above.
