I have been using Shopify for some time and want to migrate from one theme to another. May also want some styling advice for pages but mainly help moving the products / apps. The products are filtered on our current site and I don't want to lose this. As I have used shopify for some time I am pretty happy to do most of this myself but would like an expert eye with previous experience to help with the final bits. I would like someone who can provide references of previous work they have done.
