Launch time (I will not promote)

Hi community! I need your help. Soon it will be time to launch my product (iOS app) and I'm trying to make a plan on what to do during the launch and how to promote it. My budget is 2-3k$ (for first time) So far in my head it's something like this: \- Launch on platforms like ProductHunt, Tinylaunch, Microlaunch, this subreddit, Show and Launch in Pieter Levels tg channels \- Small budget in Google Ads and Apple Store Ads \- Create socials: twitter, instagram, tiktok \- Start communicating with small influencers (5-10k followers) about advertising I have also been contacted by advertising agencies who offer to run my social media accounts, I have never used such services and am not aware of the pitfalls. Ready to listen to any advice, recommendations, cautions.
