Looking for a mentorship in my startup journey

Hey, I am looking for a mentor for my startup journey, basically, I did 1 startup where we sell really early without any profit but made good connections and reputation, was one of the early engineers of my second startup which is going really well. Now I built an application on the side where I believe it has a potential to scale really well with good unit metrics. But I think I need some regular guidance along the way. What I have in mind is either I will try to scale the app a bit more (alone), and apply one of the accelerators to get a better education on these things. Or I will try personally contact the people around my network time to time but it won’t be something regular like weekly etc. If you ever had any regular guidance, where do you guys find solid people that will spare time for you? Or do you just reach out people when there is a new problem? Or do you even felt the need at all?
