Checklist of responsibilities to cover for a starting entrepreneur

Hello everyone, As someone who started a business recently, I still find it a bit overwhelming. I was wondering if someone could share some useful articles that cover the main responsibilities that a director needs to cover, including legal, accounting, etc. Of course, I've done loads of research and tried to prepare as much as I could but still, would like to double-check everything. I've been going through HMRC's pages but find it quite generic and often hard to understand. I know I can speak to a professional but I'm trying to find more budget-friendly options. Thank you very much. Best,
