6amMart UI & Stripe Upgrade

I already have 6amMart extended script and now need it to integrate car rental ,demandum service on demand , Taxi ride, 6cash payments natively. The job is customize to Enterprize grade and Installation. refresh the user interface. I want a new colour palette that matches my brand guide, a cleaner screen layout, and a more intuitive navigation menu across the customer, vendor and admin panels. All changes have to remain fully responsive and must survive future 6amMart updates.

If you have prior experience with 6amMart or similar Laravel/Flutter stacks and are comfortable working directly in Git, this should be a straightforward assignment. Let me know your timeline and any clarifying questions.
