Write some Software

Hi all, I had my magento website, at the one page checkout, under billing information, having some problem after someone code that page for me to do some editing on wordings for example fax to replace by Telephone 2 etc. But now at my Guest Checkout Page, under billing information, the STATE Column for customer to key in their STATE has disappear. 1. I need a professional that knows coding well, to help me fix this issue on the STATE column. 2. I need the STATE to remove the "required" which is the star, and make it a optional option for people to key in their state. Please visit my website at [login to view URL] and just add any item to your cart, and check out as guest, and go into the billing information and you will see the state column is gone. And let me know whether you can fix this issue, and how long will you take =)
