SHOPIFY GALLERY CREATION - SEO, IMAGE HOSTING, CUSTOM FILTERS

Description

PLEASE NOTE: THERE IS ALREADY AN ONGOING PROPOSAL FOR THIS PROJECT BUT WE HAVE CHANGED THE BRIEF SLIGHTLY.
My company is looking for a freelancer or agency to help us design and create a new gallery function within our website. We would like to most likely host this within Shopify itself and upload up to 1000 images potentially.
We are looking for the gallery landing page to function like this: https://www.rotiform.com/vehicle-gallery with filtering by model, brand, etc. Then each item on the landing page opens up a new gallery that houses information and multiple images.
The galleries themselves would look and function like this: https://brixtonforged.com/portfolio/bmw-x5m-f95-wheels-brixton-forged-pf13-r-forged-wheels/ with item description, details, and the ability to "shop the look" which will link to the products that are shown in the gallery images like the file labeled "Shop The Look"
Finally, we need to have a snippet that can be added to product pages and the homepage that will show related galleries or galleries that we select on a per-page basis.
This gallery will essentially copy functionality from both https://www.rotiform.com/vehicle-gallery and https://brixtonforged.com/photo-gallery/
