Shopify Bugs and Some customization needed.

Hello, I am in the process of developing my Shopify Store ([login to view URL]). The changes could be in the code or the customization panel as well. Please check the side and revert back with the number of changes you can execute: 1. The Search Bar need a Plain Square Box of around 250 px 2. The Pop Up page when added to card should be drop-down from the Cart Icon Itself 3. The Size Guide Button sometimes hover over the Add to Cart Button. Need proper placement for the same. 4. The sharing Icons needs to be updated. (Whatsapp, Facebook, Instagram and Twitter) 5. Full Breadcrumb needs to be added and to reduce the banner width of the same to a minimal Top Bar. 6. Create an Account Page along with My account option in Home Page near to be added. The Create Account Page will have a basic form fillup with Mobile No verification step added. 7. Social Login to be enabled. I don’t need third party app to be added since they can misuse my data. I would prefer own Oauth Application. 8. Further Small Optimizations for Mobile Site. 9. Image Images Thumbnail to be resized to a single size format. 10. Image compression to be done to optimize site performance. I am looking for Freelancer with Cheapest Price and Background Experience in the domain.
