Website button adding help

Hi, I need some "Payment" buttons added to this website, and I can't seem to get them on there, centered and in a straight line underneath the last line of text 'purchase and download' in the boxed area. They are buttons that are loaded with HTML code that point to online payment processors. The button code themselves are included in the [login to view URL] file for you as well, and also the full website code is included in the .ZIP file. I use Dreamweaver MX and any and all methods used should be compatible with that program and should be compatible with all major browsers. Should be simple for someone familar with placing items on a page. Samples and quick turnaround are appreciated. Thanks all!
