Laravel Developer Needed to Add Backblaze B2 Cloud Storage Support

I have purchased a CodeCanyon script called “GoStock – Free & Premium Stock Photos Script”, built with Laravel.

GoStock – Free Stock Photo Script (Laravel)
(Codecanyon Link: https://codecanyon.net/item/gostock-free-stock-photos-script/19407325)

Currently, the script supports the following storage providers:

Local Storage
Amazon S3
DigitalOcean Spaces
Wasabi
Vultr Object Storage

I want to add support for Backblaze B2 Cloud Storage and integrate it properly into the existing system.

Scope of Work

Integrate Backblaze B2 Cloud Storage into the Laravel application
Configure it using Laravel filesystem (Flysystem)
Add Backblaze B2 as a selectable storage option in the Admin Panel

Ensure the following work correctly with Backblaze:

Image uploads
Image downloads
Thumbnails & resized images
Public/private file access (as per current system behavior)
Keep the integration secure, optimized, and clean
Do NOT break existing storage providers

Important Notes

This is NOT a full rebuild — only storage integration
Clean code & Laravel best practices are required
