You haven't set the font for the last picture. You need to add
font-family: "Courier New", Courier, monospace;
Also, for the third and fourth pictures, you need to add
to make it bold, as in the first two. As those styles apply to all four pictures, it would be easier to set them once on the containing div .businessborder, rather than on each link individually.
You have set a background image on your links, then set the link height to 100%, which includes the size of the image. If you remove
on these, the clickable area should be confined to the text alone.
You might want to rethink the colour for those links; the yellow text on white background for "Commitment" is illegible.
