Don't listen to these other guys. I know exactly what I'm doing when it comes to ecommerce. I'll let my reviews stand testament to this fact. I have 1000s of hours of experience troubleshooting problems, developing incredibly complex extensions, and modifying different core parts of ecommerce software. The software I'd like to use to develop your site is Opencart. It's fast, fun, easy and the administration backend is simple to learn, so you can get up and running with your products ASAP. It scales extremely well and best of all, maintenance is relatively simple. I'm available around the clock when it comes to ecommerce projects, so you'll get my cell, Skype, and of course you can always just contact me on Freelancer. Thank you and hopefully we'll be working together soon.
