I see you've received many low bids.
My bid is to install a proven and well known shopping card/e-commerce product on your wordpress site, do the initial setup, and then to work with you over the phone to integrate it in your current site as well as showing you (or your staff) how to add products to your new online store before enabling it into your site.
I hope you give my bid consideration even if you don't choose to go with me.
I am Located in Hawaii, USA and would be able to communicate with you/your staff on the phone if your in the USA, or via Skype, or other online voice systems.
