Add two iframe banners to my website

I need to add two banners to my website. I have the iframe code for both and just need them coded into my site. I will give you the FTP password etc. for you to complete this project and I might need you to take that coding out so it reverts to the banner rotation that is currently in place. If this goes well I will use you for small stuff like this in the future as well. The site you will be making these changes for is bdsmplaypen(dot)com
