If you would like to start an eCommerce site, I am suggesting Woocommerce. I am using it on my store for some time now and I am pretty good at installing, configuring and customizing it. The fee listed in this thread is just a number. We will negotiate a final price based on what you need me to do. I can even upload products! Let me know if you need my services.
I don't need product uploading service. Will you install woocommerce theme and customize it to look unique?
