Very nice website!
Best of Luck. I recently started my new website also after listing on eBay for 2 years.
I did the complete opposite of you..lol. I use shopify which was real easy to set up using one of their free templates and pay the $30 a month. I also did a google feed (free), a facebook shop (free), a blog, and a social media app which posts 2 products per day on FB and IG for free. My initial investment is my time + $30 a month. Granted I only have one sale as I am still relying on my ebay business, but hopefully plan to organically build this up.
Their is a lot to say about google ads, and I know a lot of success stories, but at least for now Im going to try the organic route.
