your toll free number is in a good spot, but needs to be a larger image. you also need to show your hours and days open in that same area.
customer are also now a little cautious about ordering from sites that dont show any proof of being hackersafe, too many people are getting info they shouldnt . you should contact
Secure Transactions | PCI Compliance | McAfee Secure for Websites
as a possible solution for you.
a nice flashy presentation right on the front would be better than just showing one static image.
good luck..
