Shopify Development: Develop store based on existing design

I’m seeking a developer to alter a Shopify theme (Craft) to fit our design. The design itself was based loosely on an existing free theme, so most of the edits should be minor, but there are a few structural things that are beyond my minimal coding experience.

Desktop site prototype here (will need to match this as directly as possible): https://xd.adobe.com/view/81a826d5-c450-4c1a-a6f3-473a98a13dd8-d4fb/?fullscreen

Note: prototype isn’t responsive, but the site itself should be.

Site Features/Scope:

Responsive (Should be built into the shopify theme, but could need tweaks)
Custom Fonts and layouts (based on existing theme)
Filterable product categories
2 product page templates (1 simple one with the normal checkout options, 1 alt with an “inquire for more info” button rather than a checkout interface - button would lead to contact pg)
Blog layout (based on existing design)
About Page Layout (based on existing design)

Please bid to match the design exactly + 1-2 rounds of QA

Also, please include the word "painting" as the last word in your proposal. All other bids will be ignored for not reading the listing.
