Complete osCommerce Shop Setup

I need a developer to take osCommerce from a fresh install to a production-ready store. Please install the latest stable version on my hosting, apply a modern and clean responsive theme, and configure every essential store setting so I can start adding products the same day we launch. Payment & checkout • Integrate a reliable credit-card gateway and run a live test transaction so I can see funds settle in my merchant account. • Ensure the checkout flow is fully SSL-secured and PCI-compliant inside osCommerce. Shipping logic • Enable real-time rate calculation for Standard, Express and International shipping. I should see the correct price no matter the customer’s location or order weight. • Add clear labels and estimated delivery times for each service. General store setup • Configure store email, tax zones, currencies and friendly URLs. • Leave me with one sample product in each demo category so I can follow your structure when I start loading the catalog. • Optimise the theme for speed and mobile usability; Google PageSpeed should rate the storefront “green” on mobile and desktop. Handover At the end, share admin credentials, a brief PDF/markdown guide showing where the main settings live, and a backup of both files and database. Once I confirm a successful test order with credit card and see accurate shipping costs, the milestone is complete.
