Anybody tried combo social media ads package here ? Need feedback

Hi,

Anybody here tried buying combo social media ads package targeting regions ? We are a small brand and looking to advertise in most platforms like Meta, Pinterest, LinkedIn, YouTube, especially traffic to Website etc. But we don't want to do all on our own individually. Any good packages you have seen where an advertiser takes care of all for a fixed budget amount ? If yes, please give your recommendations. This is for innovative consumer products (e-commerce)

Thanks in advance.
