Can experienced photographers help a baby photographer out with some logistics?!

Hi! I’m starting my photography business and I’m specializing in portraits specifically. I really struggle with coming up with my pricing & making contracts. I want to offer many packages tailored to certain fields of portrait work but I’m stuck on not charging an arm and a leg but I also want to be able to profit for the amount of time and effort it takes to do a session. Currently, I have different tiers within a session type (example: For senior photos, mini, standard & premium) But I’m also super hesitant to charge higher bc I’m not entirely confident with my equipment. And I can’t afford a new camera or specialty lens at the moment. (Shooting on a Sony a6000 w a 55mm f1.4 lens for context). I was also just asked for a quote to take pictures for a big indoor/outdoor event & idk what to charge. I would love some advice from the photographer/photography community! Thank you in advanced🫶🏻
