SEO, Social Media Marketing, Help Promote My E-Commerce Business!!

Hello! I am the owner of a brand new e-commerce swimwear brand. I'm becoming overworked trying to keep up the social media, learning SEO, google shopping, instagram & facebook shopping, and overall getting traffic to my website and make sales. I'm also having trouble getting my listings on Amazon, if you're skilled with that. I'm working with a lower budget to start, but am willing to pay more as you grow my business. Help make me money so I can make you money! Looking forward to your reply.
