Not to kill dreams but Instagram isn't going to buy your idea. There's no way for you to reach them to "sell" them an idea. There's no way to reach any tech company to do this unless you have close contact with the owners themselves and even that probably wouldn't do it. You'd have to gain user traction to prove that it's something consumers want. But since your product relies strictly on Instagram, you give them all the leverage to just copy your app once you prove that traction and them just disallowing your app. Why would Instagram even need to buy it? It's not like they have any competition that they'd want you to prevent implementing your app on. At worst they'd let you just keep running your app knowing the end user must engage with Instagram.
