Ash here from the Shopify team. Welcome to the Shopify Community!
Congratulations on starting up your shop and getting your products loaded in! It sounds like you're ready to start choosing a theme and working on customizing it for your shop. Here's a link to the Shopify Theme Store! In there you can browse the free themes created by our team, as well as third-party themes developed by trusted developers. In order to access the themes on your store, log into your admin and head over to the Online Store> Themes section. On that page you'll be able to see the currently live theme as well as any other themes that you've installed. Here's some information on how to customize your theme once you choose the one you want to use on your site!
Are there any specific features you're eager to have included on your site? I'm happy to provide some theme or app suggestions to help you reach your goals!
That is absolutely understandable. The Brooklyn theme is a solid choice, and I'm happy to go over the points in your list to help clarify how to achieve them. Most of the things in your list are going to be possible regardless of the theme you use, but let's dig in!
You'll notice that in my list I left out Bespoke URL and Top Picks. I'd love to answer each of your points, so do you mind clarifying exactly what you're referring to with those two points? Also, if any of the above information doesn't make sense, or if you'd like some more clarification on any, please let me know! I hope this reply is helpful, and I'm happy continuing to assist!
