We’ve been building our e-commerce site as well. We have a plan to release the theme with basic features for an e-commerce site back to the community but it’s still in early stage.
Currently we’re lacking purchasing step which we’re planning to add in coming weeks. You can take a look at it here. (Probably you can help adding the Snipcart part?)
Initially, we’ve taken the this theme to start with so you may take a look at it too and see if it fits your requirement.
If you’re interested in, we can share our source code and take your feedback to make the theme better as well. Once the theme is ready to be published, we’ll contribute it back to the community.
