Unsure of Next Steps

Hi, all! Please forgive me if I am not in the right place. My SEO/Ads manager had some health complications pop up and is no longer able to help our small business manage our web presence. We currently have 1 Google search ad running with another one paused that isn't finished. Is this something I can tackle on my own? I'm semi tech savvy. I created our website. There are just so many videos out there, I am unsure of where to start. And, even if I hired someone I wouldn't know what to tell them as our manager was hospitalized and is unable to respond to our communications. Any videos, help, or guidance would be appreciated! TY
