New founder looking for advice: what's the most efficient way of working on things you've never done?

I'm a first-time entrepreneur and a solo founder of a two-sided marketplace. I remember when I first started building my business, I was so ambitious and wanted to work on anything and everything on my own (FOMO personality...). I wanted to learn and build up skills! After 6 months, things haven't been moving fast enough and I finally realized there's NO WAY I can do everything on my own. The advice I got from Youtube videos and books is that I need to define things (no more than 3 priorities) for myself to focus on and just delegate the rest to other talented people. Better yet, hire an assistant to help out my personal life! Yes this sounds easy--especially for people who already made money. But how do you do it when the budget is just tight (living on my savings and unemployment benefits) let along finding the right people delivering high-quality work?I've tried fiverr and so far just no luck. Just started recruiting interns so we'll see about that. But other things such as vendor agreement contract--I know nothing about this and I know I need to hire an attorney, but I figured I need to at least decide and be clear about the terms my company and my vendors can agree upon before hiring an attorney. So I've been forcing myself to learn legal knowledge...and it's been painfully, painfully slow. This is just one example. I'm also learning about food import, payment processing, shipping, etc.I'm aware my question might sound silly or even make me sound incapable of being an entrepreneur. Just really want to get some advice about this--what's the most efficient way for an entrepreneur who's just starting to work on something she's never done and just knows nothing about?
