need Responsive Design upgrade for osCommerce site
I have an e-commerce site that I've built with osCommerce v2.2rc2a. This software has worked well for me but it's become a bit outdated as it's not mobile-friendly according to google's guidelines.
As mobile is now more and more important, I need to have my site upgraded so that it's responsive and mobile-friendly.
I'd like the help of someone who's familiar with both osCommerce and responsive design.
The most important pages that should become mobile-friendly are the product pages and the home page, though if you're able to make everything, including the checkout, responsive, that would be even better.
I'll share more details about the project privately.
