Hello,
I would be very interested in assisting you with this project. I'm new at Freelancers, but don't let that put you off. I have cast knowledge of eCommerce and web design, having ran my own business providing this for many years.
I will build you a completely bespoke site, designed to your exact spec, and I will show you mock up designs and how I see the project going forward. If you are not happy with the designs or feel that I am not 'getting' your project, I will be happy to refund you. Only when I have shown you a design you are happy to go with will you be committed to it.
We can choose several platforms. I know a lot will show you Wordpress with an eCommerce plugin, Prestashop, but I think it might be worth looking at Magento too. I am very proficient with Magento.
I can show you other websites that I have created, but remember I will be happy to show you what I can do specifically for you. With massive functionality, including automatic invoice to customer, automatic notification to you, simple page and product set up (I will even assist you with this too) and full customer self management, so you end up with a totally autonomous project.
No one will do more for you, I guarantee it.
I wish you well with your search for a freelance designer, and of course hope you will consider my services. I promise to work hard with you, not just at design phase, but throughout the life of your business.
