Hi there
I'm a new new to Freelancer, but I'm not new to Shopify design/maintenance/branding. I own my own e-commerce shop ([login to view URL]) and have worked extensively in the creation of our product pages, and organization of the overall website to match my brands look/feel. As a result, your project sounds like its in my wheelhouse.
I am currently a Shopify partner, and am working with a number of clients who are moving from WooCommerce/Etsy to Shopify, so transitioning product data from one source to another is something I'm very comfortable with.
Do you currently have a theme in mind? To get things done here is what I would propose:
1. I will come up with an initial layout/organization of products based on your website and a Shopify theme or any sketches you may have for your feedback and review.
2. We'll jump on the phone and discuss what you like, and don't like about what I've come up with. I will also send you a PDF version of your site that you can markup and comment on.
3. I'll revise your sites collection/product/page organization to reflect your markups.
4. After a month of testing your live store, we'll make some revisions/adjustments if you desire for a nominal fee ($150).
I like working with clients over the course of a long period of time. Because I'm well-versed in Shopify, online retail, and branding, it'd be great to keep in touch long term and make adjustments and modifications to your site as you learn more about how people are interacting with it.
