Need Support Help

I built a Gallery 2 site for a customer many years ago. I'm no longer in this business and need someone to help the customer. Right now the admin section is not showing up (but menu, header, footer DO show on the screen). The footer is just under the header as thought a block of code was missing.

Please pm your rates and availability. I'm going to choose someone to hand off to the customer and then step back. He is a good, honest customer that pays his bills and depends on the web site for business.
