Small CS-Cart site maintenance and add-ons- redo

Hi -- I'm looking for bids on providing monthly and hourly support for our very small (one product) CS-cart site, sinoxspray.com. We need cosmetic changes and will probably add additional products over time. We need someone to make sure that the platform is correctly upgraded, configured and backed up. You'll need to provide US-based references that we can check. You need to have implemented MULTIPLE CS-Cart sites that are doing significant business in the US. Please feel free to propose additional services that you think we might need as well. Thanks, Jack
