Your site shows two links, but some thoughts:
#big ul{
display:block;
}
#big li {
display:block;
width:25%;
float:left;
text-align:center;
}
#big li a{
display:inline-block;
}
Makes the li element 1/4th of the width of its parent ul, then centers each a element in those. Add your styles as you want it to look.
