Help ranking ecommerce site selling lithium batteries.

Hey! I recently created an ecommerce site selling commonly used lithium batteries for various applications. I am determined to rank high enough in google so I dont need to advertise.

What is the most effective way to climb the rankings as an ecommerce site?
If you think you can help let me know and we can discuss, I am more than willing to hire someone to help!
