My footer refuses to center

Hello all. I’ve been struggling to get this darn footer to center. I was able to make my main content center but the footer is elusive.

Site: http://www.harvestcreativeservices.com/wp/

basic css:
div.footer_wrapper {
margin:0 auto !important;
padding-bottom: 20px !important;
margin-top:-3% !important;
}
div.footer {
margin:0 auto;
text-align:left;
clear:both;
margin-left:25% !important;
margin-right:25% !important;
padding:0 40px 75px !important;
}

css I applied to the widgets that I changed so I could fit 3 columns instead of 4:
.widget_text {
width: 350px !important; /* changed from 137px to make 3 col layout */
margin-left:-90% !important;
}

.widget_pages {
margin-top: -75px !important;
}

Let me know if there is anything else you need.
