Shopify Expert Needed – Fix Blog Thumbnails & Button Alignment (Canyon Theme)

We need an experienced Shopify developer to resolve two theme-related issues in our Canyon Shopify theme:

Blog Thumbnails in Search Results:
Our theme is set to "Adapt to Image", but blog thumbnails still appear cropped to a square in search results.
We need them to display in their original aspect ratio without affecting the layout.
Mobile Button Alignment Issue:

The "Shop Now" button needs to be centered at the bottom of its container on mobile screens.
We’ve tried CSS fixes (flexbox, absolute positioning, etc.), but it’s not aligning properly.
The fix must maintain the current layout and responsiveness.

Requirements:
Strong expertise in Shopify Liquid, CSS, and JavaScript
Experience with the Canyon Shopify theme (preferred)
Ability to debug search template image rendering
Skilled in mobile-first CSS adjustments

Deliverables:
✅ Blog thumbnails display in correct aspect ratio in search results
✅ "Shop Now" button is properly aligned at the bottom center of its container on mobile

? Quick turnaround preferred! Please provide relevant experience, estimated timeline, and budget.
