An existing retail website ( www.airarmsports.com ) needs modifications/debugging such as adding new search functions, coupon codes, non-skipable checkbox on checkout page, adding more items on homepage, etc. All updates must be fully tested and current proudction website must run smoothly without disruption, especially in the evening time of the U.S. (ideally all uploading/page changes are done in the morning of weekdays - U.S. Eastern Time). The update should be completely done before Nov. 6, 2009.
