Thanks for using freelancer, and the opportunity for me to bid on your project.
I looked at your current site and this would seem like a perfect use case for WordPress and WooCommerce. WooCommerce is a plugin for online merchants - however, you don't really need to offer anything online - the good thing about WooCommerce and your site, is that it is designed to help online merchants display their products and easily maintain a website. As such, this should make things fairly easy for you in the future. Also, if you do decide to sell online - you have the infrastructure in place - simple as flipping a switch.
We would need to spend an hour or two, going over some design aspects - just to make sure you are getting what you want, and I can help you navigate the WordPress admin - its fairly intuitive. All in all we are looking at a couple days worth of work to get you up and running on a new site.
Thanks again for this opportunity - I hope your project is a success - feel free to contact me if you have any questions, my information is in my profile.
